What is the difference between magnum and standard primers? Will I see any variations in pressures by using large rifle magnum primers as opposed to large rifle standard primers?
Thanks.
Thanks.
What planet did that logic come from?To answer your question, the difference between regular Large Rifle primers and Magnum Large Rifle primers is that the magnum primers burn longer, since magnum rounds traditionally have more powder in them.
You don't do much cooking or baking do you?Hotter and longer are perhaps the same thing?

I spoke to our reloading expert on your question. He recommends disassembly of the rounds. We have not performed any testing here at CCI/Speer to be able to tell you how much your pressures will be elevated by the use of a Magnum primer.
He went on to say that if it were him, he would disassemble, leave the primers intact and reload with a propellant that is compatible with a Magnum primer. Our Speer #13 manual lists three propellants : 760 , H414 and H380 in conjunction with the Speer 180gr. Spitzer boat tail you are using. Linda
