Should one use small pistol, or small pistol magnum primers for these?
Being as they use a smaller primer instead of the large pistol primers I fail to see where there would be a problem. As I stated in my earlier post I use small rifle primers reloading pistol calibers, CCI brand to be exact, I encounter no problems with ignition or other problems. I do not load near max, and the paper targets are just as dead as those shot with higher powder charges. Also much easier on my wrists too.
