Yes! Earlier I read about the rim thickness checking and my book on 10/22 customizing had a section on that (I recall some charts where they sampled different bullets and there were some with significant variations) and from what I recalled, they did mention it may have an effect based on your headspace (each rifle differs)...I was going to note it, but my knowledge is too rusty by now, so I
. I think it made the most sense to check if your headspace was at one extreme or the other and besides that, it was helpful to see which brands had wide variances, but those charts are very old by now. I'm also not up to that level...so many other things I'd need to get consistent/near perfect first.
So I always wondered...how many shots through would you say is expected/reasonable when someone says their gun can shoot "one hole" groups? (At least 2 I hope!
) And at what distance for .22LR?
