I realize this is off topic here, but can one of these rebore 'smiths go from 30 cal to 8mm??? At the cost of 308 ammo I'd like to go to 8 Mauser in my 1919A6 (you know - the gun with a belt). I have a 30 cal barrel that is missing the first 8" of rifling (can't imagine why). 8mm ammo is cheaper and just as fun.
