Just curious if anyone knows about wildcat cartidges based on the Breneke case, esssntially a "375 x 64 Breneke" or "416 x 64 Breneke", if they exist. I've got a Mauser98 VZ24 Brno action that my gunsmith made ready for a barrel. I am undecided as to what chambering it ought to be, so I figure I'd ask around. Thank you.
