It was explained in an earlier post that there's a 50 caliber limit on bore size for handguns that presents a practical limit to bore size. Have you seen examples of anyone skirting the limitation by building an extremely heavy 50 caliber bullet, like a 2,000 grain bullet fired from a straight-walled handgun-style case? I'm trying to predict where the future of heavy-recoiling handguns is going now that we're brushing up against various limitations.
