I have this cape gun. It's a Henry Pieper sxs with 12 gauge 2 1/2 inch on one side and what seems to be 9.3x57R on the right. I have found brass and projectiles at Buffalo Arms. They cut down 30-40 Krag brass and sell a jacketed 193 grain projectile. Initial loads with H322 and Alliant 2400 prove to be VERY accurate, but I am loading without the benefit of the proper dies. Can anyone recommend a source for 9.3x57R dies?
