[QUOTE="Philward, post: 2269347, member: 92604"] Working on a load for 115 nos bt using imr7977. Shoot the following targets the other day. Used load data from nosler for h1000 and shoot 1 round each at .5g increments from 67-71.5. 10rds with rem 9.5m primers and bullets seated at 3.300, and 10 rds with cci250 seated at 3.210(0.001 longer than nosler). No issues with pressure. It's weird that the last 5 with cci primers shot so badly, right target bottom group (I was aiming at bottom center of target edge). Maybe barrel got too warm. No velocities since I shot my Chrono with 30 nosler right before these. The right hand impact on center target is #10 of the rem string and I knew I pulled that one. Using new cases too.[ATTACH]293314[/ATTACH][ATTACH]293315[/ATTACH][ATTACH]293316[/ATTACH] [/QUOTE]
