I'm looking to design a bullet on your site for a 425 Westley-Richards. the cast diameter would be .436".
My question is I'd like to have a gas-check shank, but at that diameter, I seriously doubt a 44 mag gas check would either crimp on, or be any use.
Could you please share your thoughts on where to go with this problem, hopefully other than just staying with a plain base design.
I had thought maybe Gator-checks, being a little thicker than Hornady, might have been an option to use them?
