    After doing some 25/50 yard accuracy testing with my Ruger 10/22 Take Down, I found group size changed if forearm touched the rest - https://www.thehighroad.org/index.p...weight-and-rim-thickness-for-accuracy.850634/

    So I gifted the Take Down to my sister/BIL for my nephew/niece to shoot and bought me a 10/22 Collector #3 from PSA for $199 - https://palmettostatearmory.com/rug...nd-collector-series-rifle-od-green-31115.html

    [​IMG]

    I decided to do something different with this 10/22 which was to shoot it out of the box without any cleaning/lubing to see how many rounds it would take before needing a cleaning/lubing.

    The break-in was done with Federal 36 gr CPHP (Walmart 550 round red box) and Winchester 40 gr CPRN M22. Over 500 rounds were fired without issue on range trip #1 and #2 which were mostly fun plinking at cans and steel plates. (10/22 was left factory stock with no adjustment made to receiver bolt tension)

    On range trip #3 today, I decided to do some comparison ammo testing at 25 yards. To test "real world" plinking accuracy where targets are often shot with hot barrel, 60 rounds of Federal 36 gr CPHP (Walmart 550 round red box) were shot as fast as I could reload the magazine. I got following 6 ten shot rapid fire groups on the left using Bushnell Trophy 3-9x40mm (These groups are more consistent and smaller than groups I got with my Take Down using Federal 36 gr CPHP - I was actually happy to see these groups even though group size increased slightly as barrel warmed).

    &temp_hash=9e739da4d56cc15c26a28e812adf33ed.jpg

    25 yard 10 shot group ammunition comparison:

    The 10/22 barrel has not been cleaned since new out of the box and sufficiently warm from 60 rounds of Federal 36 gr CPHP, I continued with ammunition comparison:
    • Aguila 40 gr CPRN - Smaller group produced than Federal 36 gr CPHP was anticipated as Aguila 40 gr Lead and CPRN have consistently produced second smallest groups after CCI Blazer 40 gr Lead RN in my Take Down.
    • Armscor 36 gr CPHP - Group size was fairly consistent with what I got with Take Down. Not bad for less than $16/500 shipped copper plated 22LR ammo (cheapest ammo tested).
    • Winchester 40 gr CPRN M22 - This was a pleasant surprise as Take Down produced erratic larger than Federal 36 gr CPHP groups.
    • Federal 38 gr CPHP (275 round field pack) - I was very happy to see the smaller group with the heavier 38 gr CPHP. With my Take Down, groups I got were comparable to Federal 36 gr CPHP.
    • Federal 36 gr CPHP (525 round blue box) - This is from a case box I bought last year and was also happy to see as group size was smaller than my Take Down.
    • Federal 36 gr CPHP (550 round Walmart red box) - I wanted to do a hot barrel comparison and decided to shoot a magazine of Walmart 550 round that I used as reference. To my surprise, hot barrel produced smaller group with 7 rounds in a small cluster.
    &temp_hash=9e739da4d56cc15c26a28e812adf33ed.jpg

    Encouraged by group sizes I got so far, I repeated the ammunition comparison with now hotter barrel (groups on the left):
    • Aguila 40 gr CPRN - Group opened up a bit but I was still happy with the group size.
    • Armscor 36 gr CPHP - Group size was slightly larger but still not bad for sub $16/500 shipped cheapest ammo.
    • Winchester 36 gr CPHP (555 round box) - I got this to compare with 40 gr CPRN M22 ammo.
    • Remington 36 gr CPHP Golden Bullet - I read many reviews of this bullet producing small groups and group produced was promising.
    • Federal 36 gr CPHP (550 round Walmart red box) - Happy to see group size remaining consistent as barrel temperature increased.
    • Federal 36 gr CPHP (525 round blue box) - I always thought Walmart 550 round red box was same as 525 round blue box but the larger groups maybe due to different lot of powder as Walmart 550 round red box is from newer lot bought this year.
    And final ammunition comparison groups (groups on the right):
    • Federal 36 gr CPHP (550 round Walmart red box) - This might be the smallest group yet for Walmart red box at just over one inch.
    • Federal 38 gr CPHP (275 round field pack) - I was extremely happy with the small group size until one low shot. Still, very happy with the group size.
    • Winchester 40 gr CPRN M22 - Group size opened up compared to previous group.
    • Winchester 36 gr CPHP (555 round box) - Group size decreased compared to previous group.
    • Remington 36 gr CPHP Golden Bullet - Group size decreased compared to previous group.
    • Aguila 40 gr CPRN - Smallest group of the day.
    • Armscor 36 gr CPHP - Smallest group for Armscor 36 gr CPHP.

    With round count approaching 1000, I think a good cleaning and lubing is in order as I needed to assist a few rounds to fully chamber towards the last copy paper of groups.

    I was expecting the group size to increase as barrel got hotter but the 10/22 action/trigger continuing to break in and smoothing out could explain the smaller groups. Keep in mind, as posted in the OP, all groups were shot with "real world" rapid fire jerking of trigger I/we use for fast plinking, which was done not so as to obtain the smallest groups rather practical comparison of ammunition under "real world" plinking with hot barrel.

    Will keep you posted with range trip report #4 along with additional ammunition like Federal Champion SV, CCI Mini Mag, Federal Premium HV Match and Eley Sport.

    Thank you for helping us understand how these rounds compare with each other, and how long it takes for a new rifle to settle into its best accuracy.

    Both my Daystate Wolverine and my Umarex Gauntlet in 177 shoot a tighter groups than those at 25 yards.

    After sighing in, I was able to pop off the bugs shown in my avatar at 25 yards with my Air Arms TX200.

    Up to 50 yards and sometimes beyond, there are many Pre-charged Pneumatic air rifles that can easily hold there own against most 22 powder burners. They ain't your daddy's Daisy's.

    Great job of some real world shooting! My 10/22 gets it's best results with 1) Wolf Match Target, 2) CCI Standard Velocity, and 3) CCI MiniMags. Based on your results I'm going to get some Aquila 40 gr. CPRN and give it a try.

    This is proof that 10/22's are great for spraying lead.:D

    But we are just getting started.

    Before I do any modifications, I wanted to test "out of the box factory" accuracy using various ammunition without cleaning or lubing to the point of failure.

    After the initial cleaning and lubing, as trigger parts continue to break in, I anticipate smaller groups.

    It would be interesting to see how your groups are if you have a target on the paper that you are not destroying. Having a simple red dot that you can adjust your POI a little bit off the target POA so you have a clean target to shoot at. I bet you will shrink those groups further and take out the variable of having your previous shot holes distracting from your POA.

    If I were accuracy testing, I would be shooting at 50 yards at a dot target of some sort.

    Try just brushing out the chamber and keeping your bore "condition."

    Everyone, thank you for your comments.

    But keep in mind that this thread is not the kind of thread where smallest possible groups are pursued under ideal "best of best" conditions using highly modified/aftermarket parts. Instead, I wanted to illustrate in real world what an average out-of-the-box 10/22 can produce using various cheapest bulk ammo under worst of shooting conditions some of these plinkers are often subjected to.

    So I intentionally did not clean or lube until the point of failure of around 1000 round count where I needed to start helping a few rounds go into full battery. I will hold off parts replacement and for now only apply modifications/adjustments that could be typical of average plinkers which are checking the factory scope mount bolt tension, adjusting the take down bolt tension then moving onto shimming the barrel and sanding the stock. I initially thought about doing a light trigger job/polish with the first cleaning (to reduce round count until trigger broke in/smoothed out) but in the spirit of this "real world" thread, will hold off and allow the factory trigger to break in naturally.

    As to shooting in "real world", I am taking myself back to teenage years when I had so much fun shooting my first 10/22 without care in the world. So the 10 shot groups with hot dirty barrel (And why not slow 3 or 5 shot groups with cold clean barrel? Because they often don't tell the whole "real world" story ;)) will be fast jerking of trigger as quickly as I can place the cross hair back on target (I have to use the aid of a scope for my aging eyes with glaucoma and a touch of cataract) which I believe better represents the "real world" of fast plinking - Thank goodness, my hands are not shaking, yet. :D:rofl:

    Once the trigger sufficiently breaks in and smooths out, I do plan on doing some slow fire precision accuracy testing with best shooting ammo (In addition to Aguila ammo, I also have Federal Champion SV/CCI SV/CCI Blazer/CCI Mini Mag/Federal Match and Eley Sport waiting to be tested).

    Yes, once the trigger breaks in and smooths out, I plan on testing at 50 yards with ammo that produced the smallest groups at 25 yards.

    My standard cleaning procedure is to soak/brush with Hoppes #9 solvent to remove carbon fouling/gunk build up but as suggested by Schuemann Barrels, I will dry patch the barrel unless I see deposit that needs to be removed - http://www.schuemann.com/Portals/0/Documentation/Webfile_Barrel_Cleaning.pdf

    When shopping for Federal Match and Eley Sport, I tried to get some Wolf Match and was unsuccessful. Since this thread is aimed at real world cheap plinking, I don't plan on looking further for Wolf Match at this point.

    In my testing, Aguila 40 gr Lead RN produced slightly smaller groups than Aguila 40 gr CPRN.

    Targer Sports USA has Aguila 40 gr LRN/CPRN for $179.90/5000 with free shipping - https://www.targetsportsusa.com/22-long-rifle-ammo-c-202.aspx

    Great info - it's always good to see whole targets posted with the ammo, distance, and round count. Those are actual results that are credible. I get tired of posts that show one single target cut down to the size of a postage stamp, analyzed with software (to prove it's sub-moa), with the poster advocating one specific type of 22LR ammo. Those kind always make me wonder how many groups were shot to get that one. Thanks for sharing.

    Many, many groups, if I was looking for the "smallest" group ... been there and done that. :)

    And as to 3 round and 5 round groups ... as many members posted, they are small subset of 10 round groups (Many of my 10 round groups posted above started out as smaller 3-5 round groups), so now I only shoot 10 shot groups when testing pistol, rimfire, PCC loads - https://www.thehighroad.org/index.p...-match-ammunition.854750/page-3#post-11214637

    Over the years, many members posted that if I kept shooting, occasional "flyers" to 3 - 5 shot groups will form larger 10 shot groups and therefore, all holes on target must be counted. ;)

    Thank you. That exactly was my intent for this "real world" testing and ammo comparison thread.

    First cleaning update:

    I checked the factory scope mount screws and take down bolt and was surprised to find them all loose.

    The take down bolt was looser than finger tight, almost no tension on the bolt. Factory scope mount screws were firm but I was able to hand tighten all of them more. On the next range trip, I will incrementally tighten the take down bolt as I warm up the barrel to see if I can decrease the group size. I may try shimming the barrel next but the forward part of the Collector modular stock definitely contacts the barrel firmly on both sides.

    The 10/22 was stripped down and cleaned with Hoppes #9 and barrel was dry patched with inspection showing shiny bore. All the metal parts were sprayed down with WD40 Specialist and wiped dry (living at the coast, everything rusts here, even stainless steel gun parts and all of my steel/tools get sprayed with WD40 Specialist based on this test).

    Quite a few years ago, after I found that all of my .22s did great with Wolf Match Target, I decided to stock up on it whenever I found it. The local gun shop use to carry it and from time to time would have a sale on it. Then one day at a gun show I found the Mother Lode: an ammo dealer there had Wolf Match Target at a very attractive price and I proceeded to buy all that he had, for a total of 10 bricks! Good thing I had brought my credit card with me! Have been using it, albeit sparingly, ever since.

    The problem with stocking up with match ammo is the lube has a shelf life. Once it dries , it's no better than cheapo plinking ammo.

    How and where you store it can extend the life, but it will dry up eventually

    Range Trip #4 (Round count around 1000) Aguila 40 gr LRN, CCI SV 40 gr LRN, Federal Champion 40 gr LRN and Remington 40 gr LRN Thunderbolt were added to the testing:

    After first cleaning with Hoppes #9 solvent and lubing with WD40 Specialist (Barrel was dry patched and found clean), loose factory scope mount/ghost ring sight screws were tightened. Take Down bolt was left factory loose which was looser than finger tight.

    One magazine of Federal 36 gr CPHP (Walmart 550 round red box) were used to re-zero the scope at 25 yards. Groups #1 through #4 were shot with factory loose Take Down bolt. Groups #5 through #8 were shot with increasing amount of hand tension done with short handle of Allen wrench.

    [​IMG]

    When I got rather large groups with Federal 36 gr CPHP and Winchester 40 gr CPRN/36 gr CPHP, I realized I had left the Take Down bolt tension as tight as I could. Since increasing tension on the Take Down bolt produced larger groups, tension on the bolt was decreased to "light hand tension". (I will add these to "warming up" of the barrel :))
    • Starting with Aguila 40 gr CPRN, group sizes got smaller
    • Armscor 36 gr CPHP produced fairly tight group smaller than Range Trip #3.
    • As anticipated, Aguila 40 gr Lead RN produced slightly smaller group size than Aguila 40 gr CPRN.
    • And as expected, CCI SV 40 gr LRN produced tight small group.

    [​IMG]
    Left target:
    • Remington 36 gr CPHP Golden Bullet and 40 gr LRN Thunderbolt produced promising groups as the barrel warmed up.
    • Federal 36 gr CPHP (Walmart 550 round red box) continued to produce "OK" groups typical of 525/550 round bulk boxes
    • Federal 38 gr CPHP 275 round field pack produced promising groups initially but later shots opened up the groups
    • As barrel warmed up, Remington 36 gr CPHP Golden Bullet and 40 gr LRN Thunderbolt groups got tighter
    Right target:
    • Federal Champion 40 gr LRN - I was hoping to get a smaller group with this ammo
    • As expected, CCI SV 40 gr LRN continued to produce small group
    • I decided to shoot another group with Federal Champion 40 gr LRN only to get a slightly larger group
    • Armscor 36 gr CPHP started out with a small cluster but later shots opened up the group
    • Remington 36 gr CPHP Golden Bullet produce slightly larger group
    • I shot Armscor 36 gr CPHP again and while initial shots produced small cluster, later shots opened up the group (This is why 5 shot groups are subset of 10 shot groups)
    • Going back to reference Federal 36 gr CPHP (Walmart 550 round red box) produced consistently "OK" group
    • Remington 40 gr LRN Thunderbolt - This was a surprise as group size was on par with CCI SV 40 gr LRN

    [​IMG]
    • I shot larger clusters of Federal 36 gr CPHP (525 round blue box and 550 round red box) to see what group sizes I would produce and was not surprised by the result with mostly larger groups.

    [​IMG]
    Left target:
    • Aguila 40 gr CPRN produced a tight group.
    • Armscor 36 gr CPHP - Other than one low shot (I am not blaming the shooter), very respectable tight group
    • Shot another group of Aguila 40 gr CPRN and nice confirming small group
    • Federal 38 gr CPHP 275 round field pack - I was hoping for a smaller group
    • Winchester 40 gr CPRN M22 - My 10/22s must just not like Winchester ammo (My GSG 1911 shoots them well though)
    • Winchester 36 gr CPHP 555 round bulk - Same story as M22
    • Verification group with Aguila 40 gr CPRN to see if larger groups with Winchester ammo is due to shooter - Nope, it's the ammo
    • Verification group with CCI SV 40 gr LRN - Other than one shot to the left, very small core group.
    Right target:
    • Another confirming group with Aguila 40 gr CPRN - Nice small group
    • Once again, Armscor 36 gr CPHP started out with small core cluster but later shots opened up the group (Definitely ammo, not the shooter)
    • Was hoping for a repeat of small tight group but Remington 40 gr LRN Thunderbolt group ended up with two lower shots (perhaps due to velocity variance?)
    • Confirming group with CCI SV 40 gr LRN - Other than one shot to the left, very small core group
    • I even tried to slow fire with better trigger control but Winchester 40 gr CPRN/36 gr CPHP groups still remained scatter pattern like Federal 36 gr CPHP

    Summary (Round count around 1600):

    The factory stock Collector #3 10/22 seems to be breaking in nicely and producing some small 10 shot groups depending on the ammunition.

    For Range Trip #5, I may brush out the chamber and dry patch the bore but otherwise, leave it alone. I will bring along CCI Mini Mag, Federal Match and Eley Sport for the next trip and plan on doing some 50 yard testing.

    I have been thinking about the groups I got yesterday and since the barrel firmly contacted the stock on both sides, I decided to free-float the barrel by shimming at the Take Down bolt area.

    I cut pieces of electrical tape and applied them on the bottom of the V block. 15 layers were applied to ensure free float of the barrel as I anticipate tightening the Take Down bolt would compress the electrical tape stack.

    Barrel bore was dry patched clean and the chamber was brushed.

    Range Trip #5 with shimmed free floated barrel (Round count around 1600):

    When I got to the shooting area, a group was shooting already so I had to use an alternate shooting site for 25 yard only testing (50 yard testing will have to wait for next range trip).


    [​IMG]
    Left target:
    • 60 shots were fired using Federal 36 gr CPHP Walmart 550 round red box and I immediately noticed consistent smaller group size! Nice.
    Right target:
    • Winchester 40 gr CPRN M22 and 36 gr CPHP 555 bulk pack both produced tighter groups.
    • Remington 36 gr CPHP Golden Bullet produced tighter group
    • Remington 40 gr LRN Thunderbolt produced small core group with two higher shots
    • Confirming Federal 36 gr CPHP Walmart 550 round red box produced smaller group
    • Armscor 36 gr CPHP started out with a nice small core group but high and low shots opened up the group

    [​IMG]
    Left target:
    • Aguila/Armscor/Thunderbolt groups looked odd so I decided to tighten the Take Down bolt. As suspected, it was loose (Likely from electrical tape stack getting compressed).
    • With the Take Down bolt tightened, 2 Thunderbolt groups tightened up
    • Federal Champion 40 gr LRN produced smaller than usual group
    • CCI SV 40 gr LRN produced very small group
    Right target:
    • Federal 36 gr CPHP Walmart 550 round red box groups started to get larger so I tightened the Take Down bolt a bit more.
    • Remington 36 gr CPHP Golden Bullet produced smaller group
    • Remington 40 gr LRN Thunderbolt produced very small core group on par with CCI SV 40 gr LRN with one shot to the left
    • Federal 38 gr CPHP 275 round field pack produced one of smallest group (I am really getting happy with free floating the barrel)
    • When Federal/Remington Golden Bullet/Thunderbolt groups got larger, I tightened the Take Down bolt a bit more (I am thinking about using solid plastic shim for next range trip)

    [​IMG]
    With the Take Down bolt tight again, I decided to shoot a full page of Federal 36 gr CPHP Walmart 550 round red box to see how small of a group I could get. To my surprise, I got couple of tighter groups (My first sub one inch group with Walmart red box ammo with this 10/22)! Very nice!


    [​IMG]
    Left target:
    • As I tightened the Take Down bolt, I noticed barrel starting to touch the left side of the stock. I am thinking the electrical tape stack is compressing on one side and causing the barrel to pull to the left (Definitely will work on solid plastic shim for next range trip).
    Right target:
    • With the Take Down bolt tight again, I got fairly respectable size groups on the last sheet of target. Very happy with the last group of Federal 36 gr CPHP Walmart 550 round red box.

    Summary (Round count around 2200):

    I am definitely happy with the result from shimming the bottom of V block to free float the barrel. I am especially happy about the more consistent one inch/sub one inch groups with Federal Walmart red box bulk ammo.

    For range trip #5, I plan to do some 50 yard testing.

    Trigger pull measurement.

    With over 2000 rounds fired and one cleaning with Hoppes #9 then lubed with WD40 Specialist, trigger is breaking right at 5 lbs.

    Trigger is now noticeably smooth and lighter than new out of the box, which was around 7.5 lbs.

    To show the results of the trigger parts breaking in, on the next range trip, I can shoot comparison groups with and without barrel/V block shim.

    Range Trip #6 - 25 / 50 yard testing with hard plastic shim (Round count around 2200):

    For range trip #5, I free floated the barrel with 15 layers of electrical tape under the V block but noticed during the range session that stack of tape began to slide (I kept having to tighten the Take Down bolt) as barrel began to touch the left side of the stock. When I removed the barrel, I saw the layers of tape pieces definitely slid and measured 0.055" thick. I looked around and found a piece of plastic 0.065" thick to make a hard shim for the barrel.

    The stock channel under the V block was 0.90" wide and I cut a piece 0.85" wide by 1.0" inch long and drilled a hole to match the hole in the stock (I should have made the shim slightly longer but more on that later)

    With the shim installed, as I began to tighten the Take Down bolt, I noticed the left side of stock began to touch the barrel. There was plenty of space (0.050"+) on the right side of the barrel so I may end up sanding the inside left of the stock for true free floating of the barrel. Since the contact was slight and light pressure on the barrel allowed a sheet of paper to slide freely, I decided to go ahead with a range test.

    Since I didn't get to do any 50 yard testing on the last range session, I looked forward to doing some 50 yard testing for range test #6.

    Left targer (25 yard testing):
    • 60 rounds of Federal 36 gr CPHP Walmart 550 round red box were shot WITHOUT shim first. Groups were definitely tighter than range test #5 likely from trigger breaking in and getting smoother (Trigger pull measured around 5 lbs now). While I jerked the trigger as soon as I could place the cross hair, I did see tighter clusters forming ... very promising.
    Right target (25 yard testing):
    • 60 rounds of Federal 36 gr CPHP Walmart 550 round red box were shot WITH shim and I immediately noticed very small clusters forming. First group with single hole cluster and two flyers definitely made me smile.

    Left target (25 yard testing):
    • Aguila 40 gr CPRN - I could not believe the group size with one hole to the left! This was the smallest Aguila group I have shot with this 10/22.
    • Armscor 36 gr CPHP - This was a surprise as well. Smallest Armscor group size with two holes to the left. Things are definitely looking up.
    • Remington 36 gr CPHP Golden Bullet - I was hoping for a smaller group but the core group size did decrease compared to range test #5
    • Remington 40 gr LRN Thunderbolt - I was hoping for a smaller group but still respectable core group with two flyers
    • #2 Remington 40 gr LRN Thunderbolt - Out of curiosity, I shot a second confirming group and while started out with a tight small group, ended up with lower shots that opened up the group (Once again, 5 shot groups are subset of 10 shot groups)
    • Federal 38 gr CPHP Field Pack - This was also a surprise as this was the smallest group size shot with this 10/22
    Right target (50 yard testing):
    • Federal 36 gr CPHP Walmart 550 round red box - I guess we have come a long way since 50 yard core group size is smaller than what we started out with in range test #3 (No comment on lone hole to the left - Maybe I sneezed :D)
    • Federal 38 gr CPHP Field Pack - Definitely happy to see this group. Perhaps elongation of group is from vertical stringing? I also want to point out POI was higher than Federal 36 gr as cross hair was placed on the same vertical plane.
    • Remington 36 gr CPHP Golden Bullet - I was surprised to see the small group forming at the top until lower shots opened up the group size.
    • Remington 40 gr LRN Thunderbolt - I was hoping for a smaller group but still not bad for what is probably the cheapest 22LR
    • #2 Remington 40 gr LRN Thunderbolt - Out of curiosity, I shot a second confirming group and was excited with a tight group forming but 3 low shots opened up the group size
    • Aguila 40 gr CPRN - As anticipated, produced the smallest 50 yard group

    Back to left target (continuation of 50 yard testing):
    • Since there was almost half of paper left, I decided to shoot continuation of 50 yard testing. I repeated Aguila 40 gr CPRN and was happy with the group until high shot opened up the group size. Still, smallest 50 yard group.
    • Armscor 36 gr CPHP - Was really cheering on the small grouping until high/left shots opened up the group size.

    Summary (Round count around 2460):

    Really happy with the results of shimming the barrel. For range test #7, I want to make the shim longer to completely cover the area under the V block. And if I can't free up the space on the left side of the barrel, I will sand the inside of the stock.

    Interesting that you had "issues" at 1000 rounds. I have a 10/22 from early 70's or late 60's that has Lord knows how many rounds through it. When I was younger my best friend and I would go to his grandmothers farm and shoot 22's all day, we both had the 10/22's although his was a newer gun 80's model. We probably had 40 mags between us from the 10 rounders’ to the Mitchell 50 round "teardrop" mag...We’d load every magazine we had and them take a couple bricks and head into the woods and wouldn't come out until we ran out of ammo...those guns never failed us unless it was ammo related. We'd drive home, wipe them down and put them back in the safe and get them out the next weekend and do it all over again...those things would go 3 - 4,000 rounds or more before we cleaned them and by cleaning I mean, drop the trigger group and spray it with starting fluid or carb cleaner then WD-40, put it back together and repeat until they stopped running. It seems guns now days do not have that "reliability".

    The "issue" I had was by 1000 rounds without cleaning, some rounds started needing a bit help getting fully chambered. After the initial cleaning, no issues with chambering.

    Now at 2460 round count, I plan to do a cleaning before range test #7.
