Hello all,

I recently purchased an H&H double rifle in 450 BPE. Thinking the dimensions were the same, I purchased a set of Hornady dies and Hornady 450 nitro brass. Even after full length sizing, the Hornady brass will not chamber. The case head stops with about a 1/4” of the case sticking out of the chamber.

I tried chambering an original loaded Kynoch 450 NE and 450 BPE, both chambered fully with no issues.

Am I missing something here? Do I need a die set specifically made for 450 BPE? Any help would be greatly appreciated!
