I was sitting in my treestand with my crossbow and again got to thinking about those neat little mausers in 7.62x39 and got to wondering has any one ever improved this cartridge and if not why not? Surely with a little more room in the case and in a strong action a 110 gr should get close to 3000fps. Maybe I am too optomistic but you surely should get that 150 gr bullet fairly close to 2500 fps. I don't even think .308 bore for this cartridge, I prefer the .310-311 bore. In a improved version no unsuspecting publican would stick one in a ak! If a reamer is available from who?
