The standard twist rate for match-grade 22lr barrels is 1:16. A slightly faster twist rate may be fine for bullets heavier than 40 grains, but it doesn't seem to help the standard 40 grain match bullet.
Barrel quality and chamber dimensions have a much greater effect on accuracy.
As for best accuracy at a given distance, there's substantial trial and error testing that occurs to figure that out. For a particular rifle this will involve various brands of ammo. Furthermore, accuracy will vary between manufacturing lots for a given brand & type of ammo.
I have a Marlin 882L in 22WMR that kills whistle pigs with head shots all day long. Got one in 22LR that will do some very nice groups also. Cheaper rifle but they shoot. Chris
Here's my CZ with the NV mounted.
Eeewwww, don't touch it!
Here, poke at it with this stick.
|Let's be careful |
I have a CZ 455 in .22WMR. It is undoubtedly the best shooting, and best looking, rimfire rifle I have ever owned.
I have been investigating the same thing. I am going with an Anschutz 54 action rifle. Take a look at them you will not be disappointed.
My understanding is that the vast majority of 22LR are 1:16 twist. My Volquartsen std(based on a Ruger 10/22), my two CZs and my Anschutz are all 1:16.
But if you want, Volquartsen does make a 1:9 twist for the 10/22 and 60gm 22LR works best in that. I personally wouldn't bother with one though.
Absolutely the best choice at this price point. I was a die hard Anschutz snob until I shot a friends CZ. Very pleasantly surprised by the gun.
Another option is Ruger's newly released Ruger American Rimfire Standard Stainless (threaded) model.
