Folks, I have just prepared a couple of hundred GP11 cases, with PMC large rifle Berdan primers. Boy those little Berdan primer holes are small and easy to get clogged!
I have been using Graf's brass and some of Pierre St.Marie's loads in the past, particularly the load of 39 grains of IMR 4064 underneath an M72 173 grain pulled bullet.
Does anyone have any experience, or can tell me if these loads using the Berdan-primed brass will shoot considerably differently? What has your experience been? Thanks so much in advance!
