Hi guys, need your help! I have a .450 3 1/4" BPE Purdey top lever hammer double rifle in excellent condition. Here is my problem. I bought Hornady dies, Jameson .450 cases. I full length resized the cases, they will not fit by about 1/4" in the rifle. I have a couple of boxes of original .450 BPE rounds (not the early coiled brass)and they chamber fine. The base diameter is not the problem as the Jameson is smaller, it seems to be part way down the case the Jameson is bigger, even after resizing. thanks for your help! The island lock Purdey was built in the early 1890's and has steel barrels.
