[QUOTE="243winxb, post: 1789065, member: 97793"] Been using IMR 4350 for many years in 243 with Sierra 85 gr hpbt. Maximum in my guns was 43 grs. with hard bolt lift. New powder from 2015 at 44 grs shows no pressure sights. Having used H4350, same bullet, took more powder. I am thinking IMR 4350 has become H4350??? Same powder in both cans? Wish i had my old chronograph to check velocity. [/QUOTE]
