Magnum pistol primers

[BlitzBurg223]

I accidentally loaded 20 rounds of 9mm with magnum small pistol primers instead or regular small pistol primers. Can you shoot them or no? Thanks

First Question: What kind of powder and how much? If you are 10% under max load you should be fine.

Not sure about the HP-38, but I have run power pistol hot and switched between primers SPP-SPM CCI's and didn't see any effect at all. Didn't speed up or slow down and casings looked the same. I was trying to get some speed out of a new berretta APX 4" gun.

Thank you, I'm just wanting to be careful. I will prob just pull them and reload them.
