[QUOTE="cooperjd, post: 2230938, member: 116132"] Finally got to do a little pew-pewing today with my Dad's birthday gift to me, his 1975 weatherby mark V. .300 weatherby Weatherby Mark V 26" tube (i think) Weatherby brass, new CCI-250 178gr AH IMR-4955 1/8 turn on a Lee FCD 3.610" COAL indoor range ~70deg. 78gr--error 79gr--error 80gr--3,253 81gr--3,299 very faint ejector mark 81.5gr--3,313 little more ejector mark 82gr--3,340 blew a primer! She got hot quick! Should I try a slower powder? 4955 is around the superformance/4831 burn rate. Or should i up it with IMR-4451 in that 4350 rate with 6 or 7 less grains to start? I was hoping to get a safe 3,350 out of this one since factory 180gr accubonds shoot at 3,200. 3,300fps with a 178gr bullet will still whop an elk this fall so if 80.5-81gr shoots well I won't really complain.
