Norma Subsonic-22 LHP Ammunition Test and Review

Subsonic-22, from Norma USA, is a 40 grain lead hollow point load intended for small game hunting and varmint control.  Subsonic velocity makes this round a lower noise option over high velocity ammunition.  This load is also a good choice for use with suppressors.

Norma USA ammunition is produced by RUAG.  RUAG also produces RWS rimfire ammunition.  For those with a keen eye, you can see that the Norma brass cases share the same headstamp as RWS ammunition.  I purchased the ammunition used in this test from Graf's earlier this year.  I believe it was fresh ammunition and should represent inventory currently available at retail locations throughout the US.

Velocity, accuracy, function, and terminal performance testing were all done in a Ruger 10/22 Carbine with 18.5 inch barrel at a distance of 25 yards.  The testing results are documented in the video and data sheet immediately below.  You may need to click on the data sheet image to enlarge it for better visibility.

Wrap Up:

Norma Subsonic-22 performed great in this test.  I was well on my way to a one ragged hole 25 yard accuracy test, but blew it on the last shot.  Even with the flier, the group still fits under a dime.

Functionally, this subsonic load had no difficulty cycling the action of my semi-auto rifle. That's good news because not all subsonic rimfire ammunition will function reliably in semi-auto firearms.

Terminal performance was very consistent across all 5 test shots.  Each bullet expanded fully and penetrated to a depth of at least 8.75 inches.

At current prices, expect to pay around 16 cents per round for this ammunition when purchased by the 50 count box.  It's a little cheaper if you buy it by the 10 box brick.  If you are looking for reduced noise small game hunting ammunition, Norma Subsonic-22 should be on your list of ammunition to try in your rifle.  You may get even better results than I did.

          

Eley High Velocity Hollow LHP 22LR Ammunition Test and Review

Back in January 2016, Eley Ammunition announced three new 22LR products.  For the rimfire competitor, Eley Force and Contact.  For the rimfire hunter, High Velocity Hollow small game hunting ammunition.  At the time, I made a mental note to give High Velocity Hollow a try in the gel to see how it performed as compared to Eley Subsonic Hollow.  I was curious to see the performance differences in the areas of accuracy, velocity and terminal expansion performance.

I recently had the chance to test High Velocity Hollow with some samples provided to me by Eley USA.

Velocity, accuracy, function, and terminal performance testing were all done in a Ruger 10/22 Carbine with 18.5 inch barrel at a distance of 25 yards.  The testing results are documented in the video and data sheet immediately below.  You may need to click on the data sheet image to enlarge it for better visibility.

Wrap Up:
As I mentioned at the beginning of the article, I was really curious to see the performance differences between High Velocity Hollow and Subsonic Hollow.  You can refer back to my previous test of Subsonic Hollow HERE.

High Velocity Hollow runs about 200 fps faster than Subsonic Hollow when tested in the same rifle under similar conditions.  Eley publishes a velocity specification of 1250 feet per second for this load which falls in the ballpark of what US consumers expect from high velocity rimfire ammunition.  My velocity measurements came in quite a bit lower so I asked Eley about it.  I learned they establish their velocity in 23 inch test barrels with chronograph screens positioned at the muzzle.  My data was generated with a much shorter 18.5 inch barrel and chronograph screens positioned at 25 yards. Knowing this, it's understandable to see velocities in the 1100 fps range.

In my rifle, accuracy with this load was minute of quarter.  It didn't appear to be as accurate as Subsonic Hollow, but I've changed my accuracy testing from 5 rounds to 10 so it's not a perfect comparison.  At 25 yards, point of impact shift between the two loads was small so switching between the two shouldn't require re-zeroing of sights and optics at this distance.

I found on target terminal performance was the most notable difference between Subsonic and High Velocity Hollow.  As you can see in the image below, the extra velocity really helps the 40 grain soft lead hollow point expand, and still penetrate to a slightly greater depth than Subsonic Hollow.

Functional performance in my rifle was perfect through the testing.  I didn't experience any failures to feed, fire, or extract.

For small game hunting and varmint control, Eley High Velocity Hollow delivers higher velocity and enhanced terminal performance over Subsonic Hollow.  For those that prefer Eley ammunition, this new load is definitely worth a look, and test, in your own rifle.  Eley High Velocity Hollow is currently available at many retailers that stock Eley brand ammunition.

Fiocchi Subsonic Hollow Point 22LR Ammunition Test and Review

The next stop in my search for 22 LR subsonic small game hunting ammunition brings me to Fiocchi Shooting Dynamics 40 grain lead hollow point.  You can currently find this ammunition for about 10 cents per round at various on-line ammunition retailers.  This ammunition is made in the USA by Fiocchi of America in Ozark, Missouri.

While very familiar with Fiocchi centerfire ammunition, this was my first opportunity to gel test their rimfire ammunition.  The ammunition tested was purchased in 2017 so it should represent current production ammunition available on retailer shelves as of the date of this test publication.

Velocity, accuracy, function, and terminal performance testing were all done in a Ruger 10/22 Carbine with 18.5 inch barrel at a distance of 25 yards.  The testing results are documented in the video and data sheet immediately below.

Wrap Up:
In the video I just couldn't keep myself from using the word "consistent" as I described the performance of this ammunition.  25 yard velocity was right on target with the 1050 feet per second muzzle velocity published for this load.  Across all test shots, the ammunition reliably fed, fired, extracted, and cycled the action of the semi-auto test rifle. The terminal performance was very good with all bullets expanding to at least 1.5 times starting diameter and penetrating between 9 and 10 inches.

Practical accuracy is what sold me on this load.  The 25 yard ten shot test group measured .439" and can be easily covered with a dime.  Accuracy performance may be different from other rifles, but the field-grade Ruger 10/22 used for this test seems to like it very much.

 
I recently completed building and reviewing my ultimate lightweight small game hunting rifle.  I was a little disappointed in the accuracy results I achieved with this rifle when testing various subsonic ammunition during the review.  I had to chance to run this load through the rifle several weeks later and was very pleased with the performance. Shooting standing off hand from 25 and 50 yards, I ran a 10 round magazine through the rifle at both distances.  All 20 bullets found their mark on the steel plate, so the 16.5" Tactical Solutions X-Ring barrel also seems to like this load.  I think I have found my new small game hunting ammunition.

If you are looking for a subsonic small game hunting load, you should definitely check out the Fiocchi Shooting Dynamics 40 Grain Subsonic LHP.  

Ultimate Lightweight Small Game Rifle

The idea of building the Ultimate Lightweight Small Game Rifle (ULSGR) was hatched last year as I worked through the process of building two race rifles for NSSF Rimfire Challenge and Steel Challenge competitions. After a few false starts, and money down the drain, I landed on a combination of parts that proved to be very light in weight, but still delivered the functionally reliability required for serious timed competitions.

Purpose built for small game hunting at ranges of 25 yards or less, I wanted to build the lightest possible rifle that would function reliably with a variety of ammunition ranging from subsonic to supersonic velocities.  Avoiding the additional weight of add-on optical sights, the rifle would be fitted with windage and elevation adjustable open sights.  It would be built from "match grade" components, and be capable of shooting sub 1 inch 10 shot groups from a bench at 25 yards with ammunition it preferred.

I knew I could complete the ULSGR rifle with a total weight of less than 4 pounds, including a sling and magazine, if I followed the basic recipe I developed for my race rifles.  I set my stretch goal at 3.75 pounds and set about ordering new parts and re-purposing existing parts that I had accumulated during previous builds.  With specific colors in mind, it took several months to get everything I had in mind in all the right colors I wanted.

Completed rifles weighs 3 pounds 10 ounces

Parts List:

After a few false starts on previous builds, caused by not having all the required parts to complete a rifle, I've gotten much better at ordering all the required parts.  If you follow this parts list closely, you should have everything you need to build a complete rifle.

Trigger Assembly - Ruger BX Trigger
Stock - Knoxx Blackhawk! Axiom Coyote Tan
Receiver - Tactical Innovations Elite22F Flattop Matte Black (requires FFL transfer)
Barrel - Tactical Solutions 10/22 Open Sight Threaded Barrel Matte OD Green
V-Block - Tactical Solutions Performance
V-Block Cap Screws (2) - Tactical Innovations Blue
Bolt - Tandemkross "Krossfire"
Bolt Handle - Tactical Innovations Skeletonized
Recoil Buffer - Tandemkross "Shock Block"
Receiver Cross Pins (2) - Tactical Innovations Stainless
Takedown Cap Screw - Tactical Innovations Stainless
Sling - Ten Point Gear Tan/Green Camo
Magazine - Ruger BX Clear

If you went parts shopping today, it would cost around $750 plus shipping and transfer fee to pick up everything on the list.  Watching for sales and free shipping offers might knock a few dollars off the total.  It's not a cheap build, but I can't think of a single thing I would change about the rifle.  There isn't any room for functional or weight reduction improvement.  Also of note, the barrel is threaded just in case the process of purchasing a noise suppressing muzzle attached device is simplified in the future.   

Question Everything:

In my quest to reduce weight, I did comparison testing with several different rifle components after they arrived.  This was more for my own knowledge than anything else.

The first was the receiver.  The Tactical Innovations machined aluminum receiver was nearly an ounce lighter than a standard Ruger 10/22 cast aluminum receiver.  It was also much smoother inside and features a hole in the rear of the receiver where a cleaning rod can be inserted for breech to muzzle cleaning if you wish to do that.

I really like the Volquartsen TG2000 trigger group.  I've been using them for years in several different rifles.  I initially planned to use green one pictured for this rifle.  Before making my final decision, I compared the weights of the Ruger BX trigger and TG2000. Since this will strictly be a hunting rifle, I opted to go with the BX trigger and shave about 2.5 ounces off the build weight.  

The last comparison I wanted to share was the weight difference between the clear and black Ruger BX magazines.  I've always suspected the clear magazines weighed less than the black magazines. They "feel" lighter when you handle them.  Taking two brand new magazines out of the factory packaging, it was neat to see my suspicions were correct.  The clear magazines are 10% lighter than the black magazines.

Assembly:

The most difficult part of assembling the rifle is fitting the barrel.  If you came to the blog to read about the rifle then you are seriously interested in learning more about it, or possibly considering building your own rifle one day.  This video is for you.
 

The rest of the assembly process was very easy.  No additional fitting of parts was required.  A small drop of blue Loctite was required to keep the thread protector from loosening during firing.

On The Range:

As I anticipated, the rifle proved to be a flawless performer on the range.  It chewed through mounds of subsonic, standard, and high velocity ammunition with equal gusto. After two trips to the range, and several hundred rounds of mixed ammunition, I experienced my first failures to eject spent cases with standard velocity ammunition. After a good cleaning, it performed flawlessly again on the next trip to the range.

The 2 pound 10 ounce pull weight of the Ruger BX trigger and fully adjustable open sights both contributed greatly to accurate off-hand shooting at targets out to 50 yards.  The rifle is a plinker's dream come true and several hours of trigger therapy were undertaken in pursuit of this review.  As documented in the video, I had a great time "hunting" my steel critter targets and can't wait to get this rifle out in the woods next Fall.  

Velocity and accuracy testing was done on a portable bench using Caldwell's new Stinger rifle rest.  10 shot velocity averages were captured at 10 feet with a target placed at 25 yards.  The rifle clearly had preferences for some specific ammunition brands and loads over others.  The best groups came from both standard velocity lead round nose and high velocity hollow points.  All of the ammunition used for testing was of good quality, and represented ammunition most commonly used for small game hunting.

My only disappointment, from the range time spent with the rifle, was that I didn't find a good subsonic ammunition choice for the rifle.  I've got others available for testing, but it would have been great if one of the three varieties tested performed as well as the high velocity Mini-Mags.

Finishing Touches:

My initial thought was to use a basic 1" wide nylon web sling for the rifle.  As I was shopping for that sling, I happened to see these paracord wrapped slings.  Available in several different color patterns, this one caught my eye and I made the purchase even though it was contrary to my overall goal of minimizing weight.  I thought it just looked perfect for the rifle so a compromise was made.  It looks great and is perfectly functional even if it does add a couple extra ounces to the final rifle weight.



After my discovery that clear BX magazines weigh less than black BX magazines, I opted to use a clear magazine with the rifle.  I'm not really sure where I initially saw the reference, but I discovered that clear BX magazines can be dyed with common RIT dye.  Using a bottle of Rit DyeMore Sandstone, I ended up with two clear magazines with a rootbeer tint.  More fitting for a hunting rifle.  It doesn't make the magazines special in any way other than I can tell at a glance they belong with the ULSGR.  It was also a fun add-on project with the rifle build.


I'm very pleased with my finished rifle (as if you couldn't tell by now).  I hope the closing photo gives you some perspective on how light the rifle really is.  The partially filled half gallon water jug weighs exactly the same as the rifle.  Sling the rifle over your shoulder and you can easily forget you have it with you as you cross hill and dale in pursuit of small game.  I could have built it cheaper, but I really don't think I could have built it better.  It's a rifle I'm proud of and will enjoy for many years to come.

Total rifle weight is the same as the partially filled water jug.

22 LR Ammo Test - CCI Subsonic 40 Grain HP

This CCI load is intended for small game hunting.  Running at subsonic velocity from rifle length barrels, this load eliminates the supersonic "crack" that comes with bullets traveling at higher velocities.  This make it an ideal ammunition to use when you wish to minimize your noise footprint in the woods.

Occasionally, subsonic ammunition doesn't generate enough recoil energy to operate a semi-auto rifle.  In my testing, I had no issues with the ammunition failing to cycle the actions on two different semi-auto rifles. 

For my evaluation, I performed accuracy and velocity testing at 25 yards using a basic Ruger 10/22 rifle with 3-9 power scope.  Gel testing was done at 25 yards with the Ruger 10/22 and also another semi-auto rifle with a short barrel and suppressor.

Overall test results were good.  It would have been nice to see a tighter group on our test target, but not all rifles like all ammunition brands equally.  Luckily for us there are many different ammunition options available so we can find what works best in our specific rifle.

Velocity was right on the mark with manufacturers specification, and on target kinetic energy at 25 yards appears sufficient to humanely harvest small game quarry.

With regard to the one bullet that failed to expand, I'm left scratching my head as to why. Logically, you would expect a bullet travelling faster than a bullet that successfully expanded would also expand. As we saw in this test, gel testing can yield results that defy logic.  For me, that's part of what makes testing so interesting. 

My Thoughts:

CCI Sub-Sonic functions reliably in my semi-auto rifles.  It's accurate enough to meet my needs for small game hunting with iron sights at ranges out to 25 yards.  It is noticeably quieter than using high velocity ammunition and does not appear to sacrifice terminal performance at the lower velocity. One other thing to like about this load is the price. When you can find it in-stock, it's usually at a retail price of $9.00 per box of 100.

This load has been a staple in my ammunition cabinet for many years, but I've never had a chance to gel test it.  What I observed in the gel tests match what I've seen when using this load for small game hunting.  It's a good one.

Eley Subsonic Hollow 22LR Ammunition Test and Review

Eley Subsonic Hollow is a low-noise small game hunting round from the good folks over in the UK.  As with all Eley ammunition, it sells at a small premium here in the US with a box of 50 running about $10 to $12 at current retail prices.  For the premium price, you get Eley's legendary accuracy and quality control.  Subsonic Hollow features a 40 grain hollow point bullet that has been lubricated with a firm hydrocarbon compound for reliable function in all types of rifles.

I tested Subsonic Hollow in two different rifles.  Scoped with 18.5 inch barrel for accuracy testing.  For gel testing, I used the Ruger 10/22 and also a rifle with a shorter barrel and suppressor.  

Overall test results were very good through the Ruger 10/22.  Accuracy was outstanding and the ammunition functioned reliably.  Gel test results yielded nicely mushroomed hollow point bullets that had impacted the gel block at approximately 915 feet per second.

With the shorter barrel and suppressor, velocities dropped below 900 feet per second and our recovered test rounds showed deformation with incomplete expansion.  From this limited testing, it appears that a velocity of 900 feet per second is needed for the bullet to fully expand in the gel media we used for testing.

My Thoughts:
The most unique thing to come out of this test was actually hearing the bullet strike the gel for the very first time.  Usually the sound is masked by the report of the rifle, but with the addition of the suppressor and subsonic velocity I could clearly hear the smack as bullet impacted gel.

My personal preference is to hunt small game with an ultra-light rifle with 16.5 inch barrel and iron sights.  I like the challenge of stalking or still hunting vs. taking longer shots with a scoped rifle.  I'll need to do some follow up testing with the additional barrel length and verify 25 yard velocities are above 900 feet per second with the 16.5 inch barrel.  If they are, I would certainly add Subsonic Hollow to my short list of low-noise hunting loads.

Eley Contact Subsonic Semi Auto Ammunition Test

Eley....ammunition supplier of Olympic and World Champions also makes ammunition for the rest of us that hunt, shoot for recreation, and maybe even do a little competition shooting on the weekends.  Contact is one of the most recent Eley products to hit the US market.  This subsonic load was purpose built specifically for reliable function in semi-auto firearms at subsonic velocities.  The ammunition is manufactured by Eley in Birmingham, England and imported by Eley USA.

Contact features a heavier than standard 42 grain round nose bullet that has been coated in a special wax to minimize bullet lube buildup in semi-auto magazines and actions. Contact is a premium priced target load that can currently be found for about 16 cents per round.

For my evaluation, I performed accuracy and velocity testing at 25 yards using a basic Ruger 10/22 rifle with 3-9 power scope.  Gel testing was done at 25 yards with the Ruger 10/22 and also another semi-auto rifle with a short barrel and suppressor.

My Thoughts

Eley Contact hit all the marks I was looking for with accuracy, subsonic velocity in multiple barrel lengths, and 100% reliable function with two different semi-auto rifles. From a practical use perspective, I would consider Contact for small game hunting, varmint, and pest control where deep penetration is desired.  I would also consider using contact for rimfire silhouette competition.

My Epic Journey to Build a Rimfire Challenge Limited Class Rifle

When I travel to attend NSSF Rimfire Challenge events it usually involves a significant investment in travel time and related travel expenses. Sure it's great to catch up with old friends, meet new people, and engage in some good old fashioned competition, but the actual trigger time you get at these events is very limited. Setting personal goals for 2016 to attend more Rimfire Challenge events and improve my performance, I decided to build a Limited class rifle and pistol this winter so I could compete in both classes if the shoot organizers allowed me to do so.  I called this my travel once and shoot twice project.

I started my build with some general ideas of things I would like to include on my rifle.  The first requirement was fiber optic sights.  A FO front sight was a must have and also having a FO rear sight would be even better.  The stock had to be adjustable for length of pull and comb height.  I wasn't trying to build the lightest rifle possible, but a lighter rifle would be preferable to a heavier rifle. Finally, I wanted to limit the out of pocket expense to build the rifle by using as many previously acquired components as possible.  I'm not sure about you, but the older I get the more stuff I seem to acquire.  I made fun of my Dad for that when I was young.  I guess this is my payback.

All builds start somewhere and I started with a stripped 10/22 receiver that I scavenged from a generally disappointing Ruger SR-22 Rifle purchased several years ago for Rimfire Challenge events.  I considered reusing the factory bolt and charging handle, but decided against it after polishing on the bolt for a few hours and still marveling at how rough it looked.  Ultimately, I discovered Tactical Innovations while shopping for bolt buffers and decided to give their extra large charging handle and match grade bolt assembly a try.

I previously reviewed ATIs Ruger Charger AR-22 Stock System and liked it.  I picked up their AR-22 TactLite Stock System for 10/22 rifles with the intention of swapping out the shorter Charger handguard for the rifle handguard.  I really liked the fully adjustable stock on the AR-22 TactLite Stock.  The full length picatinny top rail would be a great place to mount the picatinny rail mounted fiber optic sights I finally found available from an airsoft supply house in China. If anyone cares, there is a huge opportunity for someone to make picatinny rail mounted fiber optic sights for rifles.

The barrel installed on the SR-22 receiver was an all steel mid-weight barrel with a seemingly unremovable flash suppressor.  It was replaced with a Tactical Solutions X-Ring barrel.  I also upgraded to the TacSol Performance V-block. While I was ordering these parts from TandemKross, I included their Shock Block bolt buffer, Twister titanium takedown knob, Eagle's Talon extractor, and a Gunsmither Bolt Bar and Extractor Tool.

The green Volquartsen TG2000 replacement trigger housing for 10/22 was something I had on hand. If I remember correctly, it was one of the blemished housings that Volquartsen would occasionally post on a large auction site.  Regardless, it has all the things you want in a match trigger like auto bolt release and extended magazine release.  It also has a crisp 2 pound pull weight.  I really like these trigger assemblies.

The first trip out to the range proved that I had assembled the rifle correctly.  It functioned perfectly, but I could tell the sights were going to be a problem.  Flipped up, the sights are traditional adjustable back up iron sights.  Flipped down, they become fiber optic sights that offered no adjustment.  After trying a few different placements on the rail, I was still 4 inches high and 3 inches left.  I made another range trip and tried various offset risers between the rail and sights, but finally threw in the towel and declared failure.  My limited rifle was a complete bust.

Brian Lawson mentions the Knoxx Axiom stock from Blackhawk! frequently.  This ultra-light stock is a drop in replacement stock for 10/22 rifles.  Before totally giving up on my project, I thought I would give the stock a try.  In place of open sights, I could use the receiver mounted Ruger scope base with a See-All Open Sight and still qualify as Limited class.  Getting this stock was a turning point in the project.

Dropping the barreled action into the new Axiom stock, I was out on the range again with the See-All Open Sight mounted.  I also swapped out the Axiom adjustable stock with the ATI TactLite stock for the adjustable comb feature.  I immediately fell in love with this 4 pound rifle and decided it was my new Open class rifle.  I added a Rimfire Rifle compensator from Allchin Gun Parts and a TandemKross Advantage Charging Handle with picatinny scope base topped off with my Burris FastFire III 8 MOA.

This put me all the way back to square one on the Limited rifle project, but I was much smarter now. I knew exactly what I wanted the rifle to look like and where I needed to go to get all the parts for the second rifle. The only different thing I would need for the new build was a receiver. I decided to try the Elite22 Flat Top Receiver from Tactical Innovations along with the same match bolt and extra large charging handle used in the previous build.

Giving up on front and rear fiber optic sights, I opted again for a Tactical Solutions X-Ring barrel with open sights.  The front sight does come equipped with a fiber optic insert.  The second Volquartsen TG2000 was originally installed in the SR-22 rifle so it was re-purposed for this build.

After a week, I had received all the parts necessary to build the second rifle.  The build came together quickly and I soon had a Limited rifle that weighed in at just under 3.5 pounds.  I've had it out to the range twice for extended practice sessions and it runs like a dream.

It was a long strange trip, but I ultimately ended up exactly where I wanted to go with my Limited rifle build.  Along the way, I found a new Open rifle that I'm very happy with.  Both rifles share many similar components so switching between them should be stress-free.

What I learned from this build process is that I should keep an open mind and be willing to try new things.  I could have given up on the build process many times, but I kept at it and tapped into the collective wisdom of other shooters for their ideas and advice.  I'm really looking forward to using these rifles for the upcoming season.  I'm sure I will see some of you on the firing line.

The Advantage Charging Handle from TandemKross serves two purposes.  It

provides a stable base for optics and allows for left side charging handle operation.

Using similar components on both rifles makes it easy to switch between

 Limited and Open classes.

This simple tool makes 10/22 bolt and extractor removal and replacement a breeze.

Use it once and you will wonder why you didn't get one years ago.  It's awesome.
