I think the chamber is ok. it shoots pretty good. test loads 52gr sierra, blc2, wsr primers by round 15 it tightened right up. groups were inside 1" with one group under 1/2"..
I think I will keep it the way it is.
I am use to loading longer oal . I have some Hornady match 68grs the bullet measures .990" long. with it seated to an oal of 2.26"
thats about .440" inside the case. putting the base of the bullet well below the shoulder, I picked up a box of federal 69gr sierra bullets. the bullets measures .885" long. .100" shorter than the Hornady but still seated well below the shoulder.
any comments appreciated.
Thanks Dave
