Ben, thanks for the kind words, glad to help.
I might add here that those bullets come from a Steve Brooks mould

Asked for a 300 grain .500 Paper Patch Hollowpoint cast of 1:30 to duplicate the original Express bullets, and the mould does exactly as asked.
IMO you can’t go wrong with a custom Brooks mould.

PS: I might add that in the same vein, our “Double Rifle Guru of the Frozen North” Cal Pappas is doing the same for me. He’s sending some 12bore conicals to try in my Lyon & Lyon before I decide on a mould.
