Shot two boxes of Berger 140 “factory” ammo and it was accurate. Good quality Lapua brass too, so very good for reloading. Measured MV for one box only: 2822 fps average out of a 30” Shilen barrel, SD was around 15 fps. ES around 40 fps. Others got better SDs, so maybe i was just unlucky. Savage Model 12. Had two pierced primers though. Might have to get the firing pin bushed. However: Never seen that before in this rifle, but i use CCI450 magnum SRP primers, which apparently has a harder cup. Very hot day in Texas, 98 F, might have contributed, but no ejector marks. No hard bolt life. Good radius on primers. But massive crater walls on some cases. I think the primer cups are a little soft.
Was i just unlucky, or did anybody else see pierced primers?
