Yes, in my case also, for an AR, there isn't
Bolt guns are different, they can have a tighter chamber plus allow longer oal's.
An AR isn't going to get the same level of accuracy as a bolt, you're trading reload/firing speed for pinpoint accuracy.
I'm not trying to over sell the technique, so these, and Kelm's, caveats are applicable.
I don't use 0.005 b/c unless I'm going to be totally anal about primers, neck turning, micro-nano-bullet seating of bullets that are btw match grade..... in short for my bullets I can see up to =/- 0.003-0.005 differences in Oal while seated, since I don't do cbto measurements. Thus a 0.010 step-wise oal will allow the target to indicate a measurable difference, if any is there.
much room to work with
until mag-limiting. For me and 123 class or below, I've got up to about 2.270.
So I can look at lengths from say 2.240 to 2.270. One of those typically has the better grouping, so I go with it.Bolt guns are different, they can have a tighter chamber plus allow longer oal's.
