Primed 45 acp with large pistol MAGNUM what do I do now??

When I started in this hobby in 2008 there was a shortage in primers going on. The only primers I could get were large pistol magnum. I worked up my loads with them. Shot 1k of them without problem. Afterward I got some regular large pistol primers. I started low, and worked my way back up. The loads were the same. I still worked up to be safe. They all shot jacketed and lead .45 ACP just fine in my M&P full sized.

If they were all I could get today. I would not hesitate to use them. Just load a few lower, and test them while working up.
 
Gas Cutting

Firing pin hole: Gas cutting is a circle of pits related to the primer cup leaking. The problem can be related to brass. In this case it was good WW brass. Swapped back to WW primers and no longer had a problem. There is no intention of flaming CCI primers. YMMV I stand by what was shared in the first post.
