[QUOTE="MagnumManiac, post: 3045529, member: 10755"] It’s a simple fact that there really is no NEED for a magnum primer. I often use a standard primer even in my wildcats on the 416 Rigby Improved case where loads run 120+ grains, never have issues until a ball powder comes into the mix, which usually isn’t quite compressed at all and the primer blast blows through the powder column, a magnum primer provides more pressure which compresses the powder and stops it blowing through it. It is visible on the pressure trace as a rise then dip in start pressure using a standard primer, it goes away when a magnum is used. I often switch between the 2 in standard cartridges too. Cheers.
