[QUOTE="Mike Matteson, post: 1790294, member: 101791"] Loading rifle rounds: Being I have hand loaded ammo for 57 years. If you are blowing out primers out, you load is to hot. That either to much power or a mag primer instead of a large rifle primes. Different reloading hand books call out different primes. So be very careful about that. The other is the case could be to long. That would cause the bolt being very hard to open. If you are loading max load after a time the primer pocket will get to large to hold a primer any longer before your case neck splits. Here several years ago i purchase a 500 Smith in a 4" barrel. Before I purchase that pistol I did some read about the round. They had switch from Large Pistol primers to large rifle primes. I built 2 loads for it. Both were H110 power, Primers were Fed. 210's, A Horndy 350 grain bullet. Max powder load is 43.7 gr. It develop velocity of 2015. Second Load: Fed. 210 primer, powder load is 44.4 gr. of H110 with a Barnes 325 grain bullet. Velocity is 2101 fps., 3186 Ft.Pd.Eng. Loading rifle rounds that hold 70 gr+. You can generally increase power load by .5 gr. at a time. Watch the primers to see what going on. If you cratering the primer you are to hot. Flatten primers is time to stop putting powder in the case. You have max it out. Possible to move the bullet back some, depending where your bullet is placed. To tight to the rifling also cause to built pressure up very quickly. Mike [/QUOTE]
