[QUOTE="backwoods83, post: 718610, member: 29890"] All rifles are different of course, but with a saami spec chamber in 243win, your max OAL should be about 2.885-2.905" before touching the lands, the amount of jump your using is what's keeping it safe, that's to high of a charge with that bullet jammed. I would not use that load in Lapua or Federal brass either due to less capacity. Full length size a case, polish the inside of the case neck, seat a bullet at 2.975", then use bolt force to chamber it, take that measurement and seat your amaxs .030" or .060" shorter, that'll give you about the best accuracy (normally) and start at 41grns, also I've found in most case H4350 works better in a 243 as does H4831sc.
