Re: what would it be? 243x57?
the 6mm has a 26 deg shoulder, but the 7x57 has a 20 deg.... with the same OAL, but the 6mm loses .2cc to the 7x57 case??? 3.48cc for the 6mm and 3.68 for the 7x57. the 243 has the same 20 deg shoulder, and is wider at the base of the shoulder.... guess if i had a reamer cut, id probably be better off going with the 6-284. i was just trying to cheat the system [img]/ubbthreads/images/graemlins/smirk.gif[/img] so the 243 stretched out .200 would be a 6mmAI without the 40 deg shoulder, since the body would be wider than the 6mm or 7x57....... dang, i thought i really had something big there!!
