    In the spirit of "Real world plinking 25 yard 22LR ammo comparison with hot barrel (Ruger 10/22 Collector #3 break in)" thread where a new Ruger 10/22 Collection #3 break in and every 5/10 shot groups were documented comparing 20+ different brand/weight/lot #s of ammunition at 25/50 yards, I ordered a Thompson Center T/CR22 based on accuracy reviews.

    T/CR22 is Ruger 10/22 "compatible" 17" firearm that can accept 10/22 parts such as magazine, etc. and was designed and built with greater accuracy in mind, starting with integral picatinny rail for mounting optics, fiber optic front and ghost ring rear sights, last round bolt hold open magazine, etc. - https://www.tcarms.com/firearms/semi-automatic/t-cr22

    I got the OD green MagPul stock model that is similar to MagPul Hunter X-22 stock for 10/22.

    I also ordered Monstrum cantilever quick release scope mount to replace Mizugiwa cantilever quick release scope mount that is showing wear after several years of heavy use for my various AR/PCC/AR-CMMG 22LR/10-22 Take Down and 10-22 Collector #3 testing (BTW, really like the QR lever mechanism on Monstrum scope mount way better than Mizugiwa scope mount and Torx head bolts were used instead of Allen head bolts).

    Quick release levers are beefy and easy to operate

    While bottom of T/CR22 looks similar to 10/22, difference is a lever on the magazine that must be pressed to load the first round (for last round bolt hold open).

    This lever must be held down to load the first round which takes a little getting used to but once you load the first round a few times, it is easy to angle the back of round to insert and then straighten out the round to load normally. The clear rear cover shows how many rounds are loaded in the magazine.

    Range Test #1 (Round Count 0) - No cleaning or lubing was done to the firearm. It was shot straight out of the box after the scope/mount were installed. Caldwell steady rest was used for the front and plastic ammo boxes/roll of blue tape was used for the rear on top of the truck tailgate.

    Following ammunition were tested on this trip and most bought within 1 year with Federal blue box/old red box/field pack bought within 2 years ago
    • Federal 36 gr CPHP Value 525 round blue box - Bulk pack
    • Federal 36 gr CPHP Walmart 550 round red box (old box) - Bulk pack
    • Federal 36 gr CPHP Walmart 550 round red box (new box) - Bulk pack
    • Federal 38 gr CPHP Field Pack 275 round - Bulk pack
    • Aguila 40 gr CPRN - Boxed
    • Aguila 40 gr Lead RN - Boxed
    • Federal 40 gr Lead RN Auto Match - Bulk pack
    • CCI 40 gr Lead RN Standard Velocity - Boxed
    • CCI 40 gr Lead RN Blazer - Boxed
    • Federal 40 gr Lead RN Champion - Boxed
    • Remington 36 gr CPHP Golden Bullet - Bulk pack
    • Remington 40 gr Lead RN Thunderbolt - Bulk pack
    • Winchester 36 gr CPHP 555 round - Bulk pack
    • Winchester 36 gr XPert - Bulk pack
    BTW, picture below shows old (Left) and new (Right) Walmart only 550 round boxes

    10 rounds of Federal 36 gr CPHP (Walmart old red box) were used to zero the scope at 25 yards.

    [​IMG]

    Left target: (These were shot essentially as initial "burnishing" rounds to smooth the barrel surface)
    • Four 10 shot groups of Federal 36 gr CPHP (blue box) were shot.
    • Four 10 shot groups of Federal 36 gr CPHP (old red box) were shot. I had one misfire that fired on the second strike.
    Right target:
    • Six 10 shot groups of Federal 36 gr CPHP (new red box) were shot. I had one misfire that fired on the second strike.
    • Two 10 shot groups of Federal 38 gr CPHP Field Pack were shot (4 more groups on next target)
    Initial impressions - While I didn't expect much accuracy as the barrel broke in, some very small 5 shot groups were forming with Federal (red box) ammo. And unlike 10/22 Collector #3 testing, Federal 38 gr CPHP Field Pack produced some very promising tight core groups.


    [​IMG]

    Left target:
    • Federal 38 gr CPHP Field Pack - I shot 4 more groups to make sure the first 2 weren't flukes. Last group formed a very small 5 shot group. Nice.
    • Federal 36 gr CPHP (Walmart new red box) - Shot as confirming groups. These are definitely smaller and consistent groups than 10/22 Collector #3 groups.
    Right target:
    • Aguila 40 gr CPRN - As expected, produced some tight small groups. As to 9 O'clock flyer on the 4th group, I must have sneezed. :D I had one misfire that fired on the second strike.
    • Armscor 36 gr CPHP - (Currently the cheapest 22LR ammo you can buy) surprisingly produced tight, consistent groups. Very happy to see this.

    Left target: (Thinking the new barrel was sufficiently burnished with copper plated bullets, moving on to lead bullets)
    • Federal 40 gr LRN Auto Match - As expected, produced very promising groups.
    • CCI 40 gr LRN SV - As anticipated, keeps on producing consistent groups. Due to slower velocity, notice lower POI below POA circles from bullet drop.
    • CCI SV and CCI Blazer were two best shooting ammo for my 10/22 Collector #3 thread. Very promising second group and look forward to 50 yard testing.
    • Federal 40 gr LRN Champion - I was happy to see smaller groups as it did not produce small groups with 10/22 Collector #3.
    Right target:
    • Remington 36 gr CPHP Golden Bullet - I was glad to see these as while 10/22 produced consistent groups, size were "meh". Out of T/CR22, these were very promising groups, especially tight 5 shot initial groups.
    • Remington 40 gr LRN Thunderbolt - Nice tight groups and no misfires. Instead of "Thunderduds", I am going to start calling these "Thunderbirds". :D

    [​IMG]

    Left target:
    • Aguila 40 gr LRN - Aguila LRN produced #3 smallest groups after CCI SV/Blazer with my 10/22 Collection #3, usually single hole groups. Very happy to see second small group.
    • Winchester 36 gr CPHP - After seeing dismal scatter patterns with 10/22 Collector #3, I was very happy to see tighter more consistent groups.
    • Winchester 36 gr LRN XPert - Same.
    • Federal 36 gr CPHP Walmart new red box - Shot two confirming groups.

    Summary (Round count 600):

    Very happy with initial break in testing and 25 yard groups. Had 3 misfires but they all fired on second firing (Walmart old and new red box CPHP and Aguila CPRN). All rounds fed reliably from the magazine and last round bolt hold open worked great. May do a light cleaning and lubing with plans to do 50 yard testing on Range test #2.

    I will check the Torx bolts on the Monstrum scope mount for tightness and do some 50 yard testing with 10/22 Collector #3 using the new scope mount.

    Plan to do 50 yard testing with more accurate ammo from 25 yard testing and further expand testing with these:
    • Winchester M22 40 gr black CPRN
    • CCI Standard 40 gr LRN (new blue box)
    • CCI MiniMag Target 40 gr CPRN
    • Federal Match 40 gr LRN
    • ELEY Sport 40 gr LRN

    I would have a hard time with the scope being mounted so high above the comb. What kind of a cheek weld are you getting with that setup?

    It is a comfortable "natural" cheek weld with eye lining up with the scope and shooting hand on the pistol grip. But the cantilever mount moves the scope too far forward for good field of view. You can see from the pictures that I have the scope moved back as far as I could.

    BTW, the Monstrum cantilever Quick Release mount is primarily for AR/PCC/AR-CMMG 22LR testing (that do need cantilever mount to move scope forward) but I wanted to test on the T/CR22 and also on the 10/22 Collector #3 for comparison using the 6-18x50mm Bushnell scope.

    Along with QR mount, I ordered Mizugiwa fixed cantilever scope mounts so I will be doing some scope/mount shuffling with my other scope mounts/rings in coming days/weeks as I have several Leupold/Trophy/Minox/CenterPoint 3-9x40mm/3-12x40mm/4-16x40mm scopes I want to test before using fixed mounts to "permanently" assigning the scopes.

    Depending on the results, I anticipated buying more scope mounts/rings.
