• Possible Downtime Alert

    I am working to migrate THR from the current cluster to a new one. I would like to get this done before the weekend, but it's unclear what the timeframe will be, as testing is still ongoing. As I am writing this the new (rebuilt) host is doing a burn-in to ensure that everything will keep running under load.

    When the migration happens users will see a Cloudflare message indicatating it cannot connect to the server. This is expected, and depending on how the migration goes this may last from 30 minutes to 3 hours - I won't know more until testing the various migration options is complete and I have finalized the plan.

    More information is available in this thread.

    As always, thanks so much for your patience.

Cobbling Together a Rimfire Silhouette Rifle

The local gun club has monthly rimfire silhouette matches. I’ve shot a couple and did ok, but nothing I’d call good. I don’t plan to buy anything for this endeavor other than ammo and maybe some scope rings. I’m basically documenting my tinkering to find the best rifle to shoot in the competition.

The competition is shot at 100 yards with optics. I have a Nikon Rimfire II 3-9x40 for the scope. I have three rifles, maybe 4, that might be suitable. One is a Glenfield Marlin 60 from 1979. Another is a later version Model 60 from 1981. I also have a Ruger 10/22 Stainless/Synthetic version and finally a Henry H001.

The competition course of fire is twice through a spinner rack of silhouettes. The rack has 15 targets, for a best out of 30 score. Front rests are permitted, but rear rests aren’t. Any hit on the silhouettes that moves them counts, including hitting the hanging stems. Targets start with a ram about 5”x8”, then pig, turkey, chicken, rat, and an assortment of shapes. The smallest is a square a little bigger than a postage stamp, maybe 1” or even 7/8” per side. I’ve got it once in about 5 tries. I don’t need to be able to hit it every time but I’d like to be able to about half the time. Of course more is better but keep in mind the limit of not putting more than a set of scope rings and maybe some match ammo into this endeavor.

I’ve been trying out my 79 Model 60 with various ammo types, as it already had the scope mounted. I typically shoot CCI SV out of it and considered it one of my more accurate rifles until I started this testing. So far I’ve tried CCI SV, CCI Pistol Match, CCI Green Tag, Aguila Super Extra High Velocity, and Eley Force High Velocity. I shot some Aguila Interceptor a while back but Marlin recommends against such ammo types.

The most accurate so far has been the Eley Force. It shot just under a 2” group at 100 yards for 20 shots. Second was the Aguila SE HV. That shot just under 3” at 100 yards for 20. All the CCI types shot over 3” and up to 3.3”. I just covered the Eley group with a quarter and 7 or 8 would have missed out of the 20. That is more than half, so Eley is the winner so far. The Eley also function better than all the other varieties.

I pulled the scope off during cleaning after todays range session. It’s still in its mout, I just have to attach it to the next rifle's rimfire 3/8” dovetail, which will likely be the Henry. I suspect the 10/22 will overall win. It currently has a set of Tech Sights and mounting the scope will involve messing with the 10/22’s fiddle receiver screws. Thus the 10/22 will be tested last.

As a runner up, I’ll test the other Model 60 but it hasn’t been too accurate over the years. However, after testing the last couple weeks, it might be a runner up. It absolutely will not run standard velocity ammo reliably, so Aguila, Eley, and some stashed Blazer and Aguila SE HV 38 grain hollow points.

I really don’t know where the Henry will fall. I’ve only really shot it with the factory sights other than some initial trials with a Simmons 4x red field scope, where it did tolerably well.
 
i have that same scope on a 795 marlin. works good up to the 75 yard plates. trigger not quite up to it a 100. just ruminating here.
on the 100 yard targets the bolt guns and their better triggers take over.
 
If your 10/22 trigger is stock, that is a big detriment to getting better accuracy from it. Doing a home trigger job with improved springs and stoning will help a bunch. (You Tube has tutorials on this.)


I went with a BX trigger rather than trying it myself. (Black Friday sale, the cost was around $60). This drop in trigger set has done a good job improving triggers on two of my three 10/22’s.

Neither of my Henry’s are as accurate as my 10/22’s, maybe you will have better luck than I with that scope mounted on yours.

Stay safe. :thumbup:
 
There's so much aftermarket stuff out there for 10/22s and so much collective experience in upgrading them that it's hard to make a good case for going with anything else.

You don't even need to start with a 10/22--I wouldn't. There are sources for bare receivers, or you could even buy an aftermarket receiver to start your build. Volquartsen makes them (steel or aluminum, your choice), but so do other companies.
 
I suspect that will be the case. Out of the three rifles, the Henry has the best trigger. I’ve not shot it to 100 yards yet but I wouldn’t be surprised to see it just behind the 10/22.

The competition has an iron-sight portion at 60 yards. It is less demanding in terms of target size. I shot that with one of the Marlins with Tech Sights. It’s tough to beat a 26” sight radius.

I suspect the 10/22 will be the winner and the Henry will be a close second and get set up for the iron sight portion. So far, the ammo testing I’ve done with the Henry also favors high velocity ammo, but it was hardly definitive.
 
I tested stock (except for optics) 10/22, 60 and 597 rifles side by side as well as a Clark custom (Walther barrel) 10/22 a few years ago. I wouldn't compete with any of the stock ones.

 
This is a pretty informal competition. I’m not looking to lay out a lot of money into it, if any. However, before I make any final decisions, I’ll test accuracy for the rest of the rifles. Right now I can hit the smallest target about half the time. I’m ok with that. If it gets better with the other rifles that’s just a bonus.

During my 45,000 round 30+ brands/weights/lots of 22LR comparison at 50/100 yards with 10/22 Collector #3 (Factory full size synthetic modular stock) and T/CR22 (Factory Magpul MOE X-22 stock), these are what I found and progression of accurizing steps I took based on THR/RFC recommendations to reduce group size and flyers - https://www.thehighroad.org/index.p...rizing-22lr-on-the-cheap.898035/post-12176951
  • Factory 10/22 trigger pull was gritty 7.5 lbs which reduced to 4.7-4.8 lbs after 3000 rounds and then down to 4.5 lbs after 3500 rounds, it still added significant input to trigger resulting in left/right POI deviation. Volquartsen Target Hammer trigger kit was the "best bang for the buck" reducing trigger pull down to 2.25 lbs (2.75 lbs after initial installation) currently at just above 2 lbs to minimize shooter induced flyers $43 - https://www.midwayusa.com/product/1004752381/?pid=163143

  • Factory 10/22 bolt comes with loose firing pin with high volume production dimensional variance and headspacing. Firing pin rising could produce inconsistent rim strike to affect primer ignition and cause flyers. CPC can pin the firing pin, machine bolt dimensions with proper headspacing and polishing service for $50 (If you shoot a lot or have extraction issue, consider adding tool steel extractor for $10) - https://www.ct-precision.com/1022rework.html


  • Factory 18.5" tapered barrel is cold hammer forged and can be quite accurate and durable but suffers from barrel harmonics specific to ammunition. I found accuracy improved with free floating of barrel and used DIY hard plastic shim under the V-block until dollar bill could freely slide around the barrel (Not necessary if using Magpul MOE X-22 stock). Best groups I could do were with CCI SV and Aguila 40 gr LRN of 1/2"-3/4" at 50 yards - https://www.thehighroad.org/index.p...rizing-22lr-on-the-cheap.898035/post-12304052

  • Bull barrel - I tested 18" Green Mountain bull barrel with 6 conventional rifling (Like 10/22 factory barrel) and 16.5" KSA bull barrel with 12 microgroove rifling and KSA has produced slightly smaller groups. I use $53 Magpul MOE X-22 stock with removable insert to free-float bull barrels and fit is tight enough to not need bedding of receiver - https://www.midwayusa.com/product/1026599966/?pid=710985
KSA 16.5" bull barrel round count at 1200, Volquartsen trigger just over 2 lbs, Power Custom bolt and Magpul MOE X-22 stock produced 3/8" - 1/2" 50 yard groups with Aguila 40 gr CPRN - https://www.thehighroad.org/index.p...lr-ammunition-comparison.908102/post-12908323

  • Scopes - 1" tube scopes: Bushnell Trophy 3-9x40, Leupold American Marksman 3-9x40, Bushnell Dusk & Dawn 6-18x50, Burris FFII 6.5-20x50 30mm tube scopes: Viridian Serac 6-24x50, Vortex Crossfire II 6-24x50, Vortex Strike Eagle 4-24x50 were tested and Burris provided best of 1" tube clarity at 100 yards. Currently Viridian Serac is on 10/22 with 20 MOA EGW rail and Vortex Strike Eagle is on T/CR22 (Due to integral scope rail so I use the 80 MOA vertical adjustment)

We have a very active 22 rimfire chicken shooter club here. Due to my tremors I have never completed. No one I have known that does uses a stock 10/22 or Marlin model 60. You might have fun but you won't win. Spend enough money and the 10/22 can become somewhat competitive. Kidd makes the ultimate 10/22 trigger but costs close to what the stock rifle does.
 
PM incoming.

To be honest, I doubt I’d win with a $2,000 Voodoo. I just want to see if I can do better this time than last time. I mean I’d like to clean the rack but at this point the wind and the two smallest plates are my biggest enemies. Each of those smaller plates is about a 50/50 proposition with no wind, which doesn’t happen this time of year here.
 
I’ve had a ton of fun assembling these two .22s, a CZ 457 and a Ruger 10/22. The CZ has a Lilja barrel headspaced for Eley ammo, and the 10/22 sports a Shilen barrel and Kidd bolt and single stage trigger. They’re in MDT Field and KRG Bravo chassis, respectively. There isn’t much difference between the two as accuracy goes, though there is some variability with ammo preference. Both will shoot under 1 moa with pretty much anything and 1/2 moa (sometimes better) with their chosen ammo (Eley, Lapua and SK, usually). I am totally happy with these rifles but if I were to do it again, I’d buy used rifles at the start. A used 10/22 can sometimes be found for around $100 and the customization and accurizing options are seemingly endless. @LiveLife has about the most extensive compendium of ammo testing I’ve ever seen and his post above is an excellent reference. With that said, every .22 is an island unto itself and presents a journey challenge to find not only that ammo genus, but also lot number, that works best and most consistently. Some people win the lottery off the bat and get factory rifles that shoot like the Dickens but most do not. It’s just an invitation to have some fun. :)

If you don't want to buy a CZ or Tikka, I'd focus on the 10/22. Some are remarkably accurate as they come. If not, there are dozens of upgrades easily done. Stock, your other rifles could shoot as well with the right ammo. But there are no easy upgrades for them.
 
Scope shipped out with ETA of Friday.
USPS tracking shows scope is "working through the network" with delay.

"Winter storms and severe weather impacting delivery
Heavy snow, freezing rain, icy conditions, and severe weather events from the Midwest through the Northeast U.S. may impact the processing, transportation, and delivery of mail and packages. Please allow additional time for final delivery of your item."​
 
It did not arrive in time to save my Henry ammo test. The green circles highlight individual groups of the same ammo at 100 yards. SK Semiauto is the one on the left. CCI Green Tag is on the right. I haven’t measured them yet but they are roughly 4” groups.

So if none of my rifles will shoot up to what I want to do, is Shaw a good barrel to try for upgrading the barrel? The less obvious improvements like triggers and the improved V-blocks and bolt improvements will come first if necessary, but a barrel is the most obvious thing to try.
 
How old is your 10/22? I'd have to get the trigger light and crisp before I'd even consider any other upgrade. Willing to bet the trigger pull costs you more accuracy than than the barrel or the v-block.

Turning a stock 10/22 into a respectably accurate 10/22 starts at about $500 and goes up to used minivan prices.
I've been in and out of that rabbit hole enough times to have become convinced that a 10/22 is never the answer for my needs. If you want a customized 10/22 just to have one, by all means go for it.

If you want something for your intended purpose and to at least have a chance to be competitive without going whole hog, just go buy a Savage MKII. Plain Jane heavy barrel with synthetic stock can still be found for around $250-$275. You'll likely double that amount and still not get the Ruger to consistently do what you want.
 
is Shaw a good barrel to try for upgrading the barrel? The less obvious improvements like triggers and the improved V-blocks and bolt improvements will come first if necessary, but a barrel is the most obvious thing to try.
Bull barrel is definitely an improvement over 10/22 18.5" factory barrel in terms of accuracy and maintaining that accuracy as barrel heats up. (BTW, I use factory V-block with bull barrels)

But if you have Ruger Target barrel, as @Howland937 posted, trigger upgrade would be my recommendation first as $43 Volquartsen Target Hammer kit, which reduced trigger pull down to just over 2 lbs definitely reduced shooter induced movement of muzzle that increased group size. Next would be $50 CPC reworking of factory bolt as pinning of firing pin better ensures more consistent rim strike/primer ignition to reduce flyers. (Barrel swap won't address rim strike/primer ignition issue along with headspacing of bolt to produce flyers and increased vertical stringing from lower velocity rounds, especially when shooting longer distance to 100 yards)

These two upgrades could reduce group size down towards 1/2" more consistently at 50 yards, especially if you already have Ruger Target barrel (And if you haven't free-floated your barrel yet, I would suggest that as well to see if group size reduces). If not, then replacement bull barrel could reduce group size further towards 1/2" and smaller more consistently less affected by barrel heating up. (If your synthetic stock won't free-float bull barrel, Magpul MOE X-22 will with forearm insert removed and receiver to stock fit is tight enough to not need bedding of receiver to stock)

BTW, Shaw Barrels is running a sale on 16.5" bull barrel with target crown for $105 - https://www.shawcustombarrels.com/shop/product/1022®-.920-bull-barrel-16.5-blued/433

I plan to try the 10/22 this weekend with various ammo to see what it’s capable of now. I have some CCI SV, Green Tag, SK Semi-Auto, and SK HV Match.
 
CCI SV shot best out of several standard ammo grades when I first got it. That included Aguila SE HV, Norma Tac, and Blazer.
