    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! :eek:
    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!

    Art, I have, but didn't see any Berdan primed specific loads. This is where I got my load of 39 grains of IMR 4064 under a 173 grain M72 pulled .308 bullet. Do you know of any, or especially any difference between Boxer primed and Berdan primed?

    Aside from being more trouble than they're worth, the loads for berdan and boxer primers are the same.

    Matt,

    That's real good brass and if you work up a load, everything should work well. I'm reasonably sure the case capacity is about what you'd see out of boxer primed cases. I would work up loads starting low, because the GP11 are military cases and are likely to have thicker walls.

    Regards,

    Dave

    Where did you get the primers? NOBODY around here carries the Berdan primers, and I've got a lot of Swiss brass saved up.

    Someone on gunbroker - when I purchased them he was selling them on the auctionarms web site, but since then, I have heard that he has moved to gunbroker.
