"Real World" cheap/bulk 22LR ammunition comparison

[LiveLife]

What is the scope mount? I presume that’s a pistol type scope?

Yes, it's long eye relief pistol scope bought from Amazon but looks like it's now sold by AIM - https://www.evike.com/products/26682/

After being impressed with $20 Field Sport micro red dot (Now $26) that co-witnessed with Magpul MBUS on my ARs based on this torture test of red dot by repeated hammering with water bottle, I ordered the Field Sport 2-7x32mm scope for IMI Defense and Fab Defense pistol scope mount comparison - https://www.thehighroad.org/iNndex.php?threads/new-glock-pistol-scope-mount-uses-frame-trigger-pin-for-more-solid-mounting.923430/

Since both mounts clamped to polymer accessory rail of Glock 22 which flexed, obtaining repeatable zero with the scope became an issue. Fab Defense addressed this issue with a new mount that has rear pin that replaces Glock frame/trigger pin. When I saw a duplicate Fireclub version for $5, I immediately ordered to review - https://www.amazon.com/FIRECLUB-Tactical-Flashlight-Universal-Picatinny/dp/B01E732I3W/ref=sr_1_27

Rear of mount replaces frame trigger pin with threaded pin and even with the weight of the scope, there is no side to side or vertical movement of mount unlike IMI/Fab Defense mounts.

Replacement pin ends are threaded

Factory frame trigger pin replaced with threaded pin for the mount

Raised mount allows use of iron sights

Access to slide/disassembly lever were not blocked

I am interested in your ammo updates, you always provide good unbiased info.

I hope your luck is better than mine with the Wildcat. It is the only 22 rifle I have not kept, I never did get decent accuracy from it.

Thank you.

As to Wildcat, when I returned Savage B22 Precision due to shipping damage, I decided instead to get BCA 22LR upper to test AR22 platform as I may revisit buying Savage B22/Wildcat in the future - https://www.thehighroad.org/index.p...r-ammunition-comparison.908102/#post-12365519

Testing Platform: 50/100 yard groups shot with modified Lead Sled Solo (Rear wedged to immobilize swing arm) on Lifetime 4' table:

• 10/22 Collector #3 with factory 18.5" barrel (Round count 6500, bore brushed every 2000 rounds/three times with Hoppes #9/copper bore brush with 3 passes each brushing) - Volquartsen Target Hammer kit trigger 2.25 lbs (Trigger round count 2500, Patriot Precision Gun Works Enhanced Trigger Spring kit) - Barrel free floated with plastic shim under V block - Rear of receiver better secured to stock with 1 strip of electrical tape - Tactical Solutions V block - Pike Arms red bolt buffer - CPC reworked pinned factory bolt/CPC extractor - EGW 20 MOA scope rail - Viridian Serac 6-24x50mm - Viridian 30mm scope rings
• T/CR22 with KSA 16.5" bull barrel (Barrel round count 1000, Rifle round count 3500, brushed once with Hoppes #9/copper bore brush with 3 passes, two .02" barrel shims used with KSA barrel) - Volquartsen Target Hammer kit trigger 2.0 lbs (Patriot Precision Gun Works Enhanced Trigger Spring kit) - Barrel free floated with factory Magpul stock - Rear of receiver better secured to stock with 1 strip of electrical tape - Factory V block - Pike Arms red bolt buffer - Power Custom Match bolt (Titanium firing pin/extractor) - Vortex Strike Eagle 4-24x50mm - Viridian 30mm scope rings

Range Report:

Trip to the shooting area was delayed by head-on collision accident clean up that blocked both lanes (I was not involved). Since range time was limited, I focused on shooting 50/100 yards reference groups with Aguila 40 gr CPRN then rushed through initial 2022-2023 new stock ammunition along with 2019 stock ammunition. Regular copy paper target was used with blue bingo dauber to mark POA.

NOTE - Old stock Aguila 40 gr CPRN (Boxed, Lot # 30EK27 Aguila Prime) will be used as reference at the beginning, during and end of each shooting session for comparison (If Aguila groups remain similar, group size variation is from ammunition, not rifle or shoote; although, shooter fatigue will be a contributing factor towards end of shooting session ). Ammunition tested will be new stock purchased in 2022-2023 unless noted as 2019 stock. Lot number of ammunition indicated inside parenthesis. Groups were v center to center. After verifying scope zero, groups were shot as fast as Ruger 10 round rotary magazine was reloaded. There was no cooling down of barrel other than walking to replace targets.​

​

With shooting session that could last hours, suspicious groups shot towards end of session due to shooter fatigue will be repeated at the start of next session. (ETA: This won't be done now as I decided to shoot old/new stock side by side to remove barrel warm up/shooter fatigue variables - https://www.thehighroad.org/index.p...nition-comparison.908102/page-2#post-12732083)​

Reference 50 yard groups:

Top row: After verifying scope zero with left 2 groups, blue bingo dauber was used to mark POA. All 5 shot groupes measured 1".
Bottom row: 4 more groups were shot to verify consistency with left 3 groups measuring 1" or less with 4th group opening up to 1.5" (Can you say shooter fatigue? Just kidding)



100 yard groups:

Two 100 yard groups were shot after verifying scope zero on another copy paper target. I forgot to bring the bingo dauber for the 100 yard walk to target and used short strips of electrical tape to mark POA. Both groups measured 2.75".



With 50/100 yard groups shot, I started the ammunition comparison with three I was most curious with: New lot of Blazer 40 gr LRN boxed and new Blazer 38 gr LRN loose bulk 525 round pack. Of course, I was curious about the only 22LR that produced consistent duds during my 10,000+ round testing (Where even Thunderbolts were 100% reliable), the Winchester M-22 40 gr CPRN.


Top row: 2 reference Aguila groups were shot measuring under 1.25" followed by Blazer 40 gr LRN (boxed - H21DA07) measuring 1".
Bottom row: Blazer 38 gr LRN (loose bulk 525 round - A03EE80) groups measured slightly less than 1.75" and 3.25". Winchester M-22 40 gr CPRN (Black bullet, loose bulk 1000 round pack of two 500 rounds - 2TH10M) groups measured 1.75" and less than 2.5".




Top row: 2 reference Aguila groups measured 1.75" (I think I pushed the low shots) and 1". Hotter Thunderbolt (loose bulk - E28WB1234) grouped above POA and measured 2.25" and 1.75".
Bottom row: 2019 stock Armscor 36 gr CPHP (boxed - 0731418) groups measured less than 2.25" and 1.5". Winchester M-22 group #2 produced 2" and 1.5" groups (In case you are wondering, bottom two holes on left group is touching). (NOTE: Only dud/failure to fire was produced by Winchester M-22. Ejected round showed nice indent on the rim which fired on the second chambering.)




Top row: Blazer 40 gr LRN group #2 produced 1.5" group (0.75" 4 shot core) and slightly larger than 0.5" group. Blazer 38 gr LRN group #2 produced 1.25" and 1.75" groups.
Bottom row: 2 reference Aguila groups measured under 2" and 1.25". Surprised by higher POI of second group, I fired another round and decided to conclude the shooting session (It was starting to get dark).



Due to road accident induced limited time constraint range session, I feel many groups were rushed and may repeat some groups to verify on next range trip. If THR members have request to do more comprehensive testing (Let's say increase sample size for particular brand/weight/lot of ammunition to 4 groups or 8 groups), I can expand the sample size.

Due to road accident induced limited time constraint range session, I feel many groups were rushed and may repeat some groups to verify on next range trip.

While making cinnamon rolls for wife, I thought about barrel warm up and shooter fatigue with time constraint rush to reshoot some of the groups; but then realized best approach to conducting comparison of "old stock" from 2019 to "new stock" from 2022-2023 maybe to shoot same brand/weight but different lots side-by-side.

This way, despite shooting variables related to firearm/shooter, holes on target will still give us usable "comparative" data in terms of group size between old and new stock. So if new stock shoots same/better/worse than old stock, we should be able to determine that regardless of group size, barrel temperature and some regards to shooter fatigue.

Finally!

47 brands/weights/lots of 22LR ammunition comparison continues - https://www.thehighroad.org/index.p...nition-comparison.908102/page-2#post-12733155

NOTE: There's been a change to testing platform as 10/22 Collector #3 with 18.5" factory barrel was sent to THR member at member's request - https://www.thehighroad.org/index.p...-unlimited-budget.912629/page-4#post-12799313

So, 10/22 receiver (Round count 7000) was mated to KSA 16.5" bull barrel using two .02" barrel shims and factory V block (Barrel round count 1000) - Volquartsen Target Hammer kit trigger just over 2.0 lbs after Patriot Precision Gun Works Enhanced Trigger Spring kit (Volquartsen trigger round count 3000) - Power Custom Match bolt (Titanium firing pin/extractor) - Barrel free floated with Magpul MOE X-22 stock from T/CR22 - Pike Arms red bolt buffer - EGW 20 MOA scope rail - Viridian Serac 6-24x50mm - Viridian high profile 30mm scope rings (I may need to get lower rings as stock on MOE X-22 angles down)

S&W factory barrel (Barrel round count 2500) was installed back on T/CR22 receiver (Round count 3500) using Tactical Solutions V block - factory pinned bolt - Volquartsen Target Hammer kit trigger 2.0 lbs after Patriot Precision Gun Works Enhanced Trigger Spring kit (Volquartsen trigger round count 1500) - Pike Arms red bolt buffer - Vortex Strike Eagle 4-24x50mm - Viridian 30mm scope rings



Modified Lead Sled Solo (Rear wedged to immobilize swing arm) was used on Lifetime 4' table. Harbor Freight measuring wheel used to set 50 yard targets along with HF open reel measuring tape.



Range Report:

NOTE: Regular copy paper target was used with purple bingo dauber to mark POA. Old stock Aguila 40 gr CPRN (Boxed, Lot # 30EK27 Aguila Prime) was used as reference at the beginning, during and end of each shooting session for comparison. Old stock ammunition were purchased in 2017-2019 and new stock ammunition purchased in 2022-2023. Lot number of ammunition indicated inside parenthesis. Groups were measured center to center. After verifying scope zero, groups were shot as fast as 10 round rotary magazine was reloaded. There was no cooling down of barrel other than walking to replace targets. Ammunition tested were stored indoors at around 60F. Ambient temperature 54F.

realized best approach to conducting comparison of "old stock" from 2019 to "new stock" from 2022-2023 maybe to shoot same brand/weight but different lots side-by-side.

This way, despite shooting variables related to firearm/shooter, holes on target will still give us usable "comparative" data in terms of group size between old and new stock. So if new stock shoots same/better/worse than old stock, we should be able to determine that regardless of group size, barrel temperature and some regards to shooter fatigue.

Rain was forecast later in the afternoon so in a rush, did not get to always do side-by-side old/new comparison (Will attempt to always do old/new comparison). After scope was zeroed with reference Aguila 40 gr CPRN, groups were shot with POA at the center of purple dot.

• Top row: First Aguila 40 gr CPRN (30EK27 Aguila Prime) group measured 1/2". Second group measured slightly larger than 1/2" with shot to the right. First Federal Value 36 gr CPHP loose bulk 525 blue box (1SP181) group measured 1.5". First Federal Value 36 gr CPHP loose bulk 550 red box (16A092) group measured slightly larger than 1". (Note higher POI of 525 blue box vs lower POI of 550 Walmart exclusive red box indicating slower muzzle velocities)
• Middle row: Second Federal Value 525 blue box (1SP181) group measured slightly less than 1.5". Second Federal Value 550 red box (16A092) group measured 1.25". Remington Thunderbolt 40 gr LRN loose bulk (E18HC1236) groups measured 3/4" and slightly less than 3/4".
• Bottom row: Armscor 36 gr CPHP boxed (0731418) groups measured 1.75", slightly less than 1.25" and slightly larger than 1.25". Confirming Aguila reference group measured less than 1/2".

• Top row: First old CCI SV 40 gr LRN boxed (40006 Rev D) group measured 1/2". Second old CCI SV group measured 3/4". Surprisingly, first new CCI SV 40 gr LRN boxed 50 round (D06DA01 40006 Rev G) group measured slightly less than 1.5". Second new CCI SV group measured 1/2".
• Middle row: CCI MiniMag 36 gr CPHP boxed 100 round (40237 Rev E) group measured slightly larger than 3/4". CCI MiniMag Meat Eater 36 gr CPHP boxed 300 round (42054 Rev A) group measured 1". Federal AutoMatch 40 gr LRN loose bulk 325 round (L101401) groups measured 1.25" and 1".
• Bottom row: Federal Field Pack 38 gr CPHP loose bulk 275 round (14P171) groups measured slightly larger than 3/4" and 3/4". It started to rain and confirming Aguila reference groups measured 1/2" and 3/4".

 

[DMW1116]

This all confirms what I’ve been seeing in my rifles overall, though some are quite picky. My Marlin 60 shoots CCI SV really well. Aguila SE High Velocity 40 grain is a very close second, based on 100 yard groups. It also shoots Thunderbolt pretty well, in spite of what people generally think about it.

My Henry also shoots the Aguila SE HV really well. It does not like the CCI SV as much. It’s zeroed for Thunderbolt and shoots that nearly as good as the Aguila. It also really likes the Federal Automatch from Walmart. These are based on shooting the factory sights at 50 yards and some initial testing at 50 yards with a fixed 4x scope.

I have another used and abused Marlin 60 that also likes Aguila and Automatch. It’s had a rough life and isn’t as accurate as the other one, but likes those best. It currently sits in original factory form but testing was done with a scope, either a 4x or 3-9x from Simmons.

Finally the most picky rifle I have is my newest, a stainless 10/22. It shoots anything standard velocity well, with CCI SC taking the lead. Anything high velocity just doesn’t keep up. That said it has been 100% reliable with all ammo I’ve tried, even more so than the manual action Henry.

 

[LiveLife]

BTW, all ammunition were 100% reliable with no duds.

47 brands/weights/lots of 22LR ammunition comparison continues - https://www.thehighroad.org/index.p...nition-comparison.908102/page-2#post-12733155

"Houston, we have a problem"

In the "Real World" sense, subsequent range trip found KSA bull barrel thread protector to be loose (Likely from Hoppes #9 solvent working as penetrating oil) and started to increase group size regardless of ammunition type. Once I removed the thread protector, reference Aguila 40 gr CPRN produced nice single hole group of 1/2". So loose thread protector was acting like barrel tuner that was moving all the time.

I am planning to repeat the groups from post #32.

Also, I ordered another rifle rest so will test on the next range trip (35 lbs with integrated front weight).

 

[patmccoy]

Surprisingly, first new CCI SV 40 gr LRN boxed 50 round (D06DA01 40006 Rev G) group measured slightly less than 1.5". Second new CCI SV group measured 1/2".

This MAY have been from the loose nut, BUT it also may show the possibility of accidentally getting the worst five rounds in the box in the first group and the best five rounds in the second group. This is why at lest thirty rounds are needed to make assumptions that are 90% valid.

 

[Ignition Override]

Even with a shortened recoil spring in my S&W M&P --Standard-- .22LR handgun, some bulk ammo (about five years old) has primers which either won't ignite, or won't blow the slide back enough to eject.

If almost every brand which You use Cycles your gun, be glad. . Be fruitful and multiply your shooting.

I agree.

CCI SV has consistently produced around 1/2" groups during the 10,000 round testing to where I stopped verifying groups (Now I use Aguila 40 gr CPRN as reference). I tested CCI SV mainly to compare old vs new as some members have posted new lots may not be as accurate as old lots. And since I discovered loosening of thread protector affecting group size, I will repeat all groups with the thread protector off.

47 brands/weights/lots comparison is now mainly for old vs new but previous 10,000 round testing was done with factory 18.5" 10/22 barrel which was quite selective on ammunition (6500 round count/3500 round count on T/CR22). Current comparison will be done with 16.5" KSA bull barrel to provide comparative group size for members using non-factory barrels.

Even with a shortened recoil spring in my S&W M&P --Standard-- .22LR handgun, some bulk ammo (about five years old) has primers which either won't ignite, or won't blow the slide back enough to eject.

From the myth busting thread, we found when particular ammunition failed to ignite, pulling the bullet revealed priming compound had moved away from the rim indicating perhaps transport/handling vibration/shock could have loosened the priming compound away from rim (And loose bulk packaging experienced more duds than boxed packaging which better protects the rounds) - https://www.thehighroad.org/index.p...ud-why-dud-thread.893062/page-2#post-12273202

If almost every brand which You use Cycles your gun, be glad. . Be fruitful and multiply your shooting.

And that's what I found during the 10,000 round testing. Ammunition purchased within 6 months of testing were essentially 100% reliable until carbon/fouling build up required cleaning of brand new 10/22 and T/CR22 (And at the end of testing, any feeding issues were addressed by new 10 round Ruger factory magazines).

Only ammunition that was not reliable with several duds per box was Winchester 40 gr M22, and new lot of M22 purchased in 2023 was the only ammunition that experienced duds when all other ammunitions tested were reliable so far (Restrike of rim did not produce ignition). So based on my testing, Winchester M-22 lot #2TH10M (I do not have any old M22 left) produces several duds per box in 10/22 and T/CR22. YMMV
