I need some advice. I have a recently purchased Model 10 .308, accustock and accu trigger. I shoot in F class /TR. The rifle with various loads will group about 1-1.25moa. I would like to improve this to .5-.75moa. My plan is to replace the barrel with a fully chambered Shilen. I've read previous posts about determining the barrel shank size but I'm not sure if mine is large or standard size. The barrel diameter directly in front of the shank is 1.056". I don't want to order the barrel until I'm sure of the shank size.
Also will the accu stock present any unforeseen problems when a new barrel with a similar contour (1.060 infront of the threads and .800 at the muzzle) is placed?
