I have some magnum small pistol primers (which I would like to "burn up") and the reloading data I have found recommends small pistol primers for 9mm Luger. I will be using Accurate Arms AA-7 powder 115 gr. Rainier round nose bullets.
Here's my question: If using magnum small pistol primers verses small pistol primers, how much of a powder reduction would you recommend to keep me safe? I have heard from only one source to reduce the starting load .5 grain for starters.
I instinctively "start low and work up".
The magnum small pistol primers I would like to "burn up" are CCI no. 550's and the firearm is a Beretta PX-4 Type F semi-auto with a 4" barrel.
Suggestions would be appreciated!
