Changing to magnum primers
After loading about 1500 9mm rounds, I finally ran out of standard primers. I do have CCI magnum primers on hand and have considered using them (I would reduce the load). I am shooting a 129 gr lead bullet over 3.5 gr of Bullseye. This will be used in a Beretta 92F.
My question: If I would switch over to the magnum primers roughly how much should I reduce the powder load? I know this is a question that has no right answer but a ballpark figure would be helpful. Thanks

Buy some standard primers. There is no way to figure how much a magnum primer will increase pressure, and in the small 9 x 19 case, using a fast flake powder like Bullseye, a magnum primer is not needed.
