Reeder Custom Guns - Is there any issue using magnum primers

For non magnum loads?

cause and ill effects.

I'VE HAD FOR A LONG TIME WITH STANDARD SIXGUN LOADS USING UNIQUE AND OTHERS.

Federal cases. i backed off and worked up loads. Didn’t have any issues.

In the .510 GNR revolver with some powder (I’ll look) and I saw a stark 150 fps difference in Magnum primers vs the same charge,bullet,gun using STD. Primers. Just saying you might consider a change in the dynamics. FWIW.

Would start over in working up your load, but shouldnt

NONE HERE I USED UP 5,000 FED # 155s

I used WSPM for those pesky 45 ACP

I’m a bit fuzzy but remember testing mag vs std
