[QUOTE="bruce_ventura, post: 1091267, member: 34084"] I'm in the same boat. I now have a 7 WSM load that shoots well in my rifle (group size~.75" ES at 100 yds for 5 shots), but the MV ES is high: 40 - 50 FPS for 5 shots. I used annealed cases for the last group of handloads. I'm thinking it's the Fed 215 magnum primers and will try standard long rifle and bench rest primers next. I have to switch over to a new lot of H1000, so now is the time to explore other primers as well. When I find a primer that minimizes MV ES I'll dial in a charge weight for the new lot of propellant.
