I know my 357 rugger black hawk had a avaliable 9mm cylinder. dont no how well they shot. I am all for a heay'r bullet hunting pistol. the good thing with my amd 65 pistol is it will shoot 250 yards plus. the bad thing is it shots 250 yards plus meaning that were we hunt is still a shot gun / pistol only zone and the visibilty is some what limmited at times. that last thing I want to do is hit a farm house or worse 2 miles away that I did not know about. some thing with less range withg more knock down power is what I am thinking .although I have shot deer out to the 250 yard range with the 7.62x39 I was not impressed with the bullet expansion bolth deeer this year with pmc sp ammo had very little expansion and were shot clear through. were the The amd realy shined was the abilty to take follow up shots hard to do with a TC Contender. A 9mm with a 200 grain bullet would be more to my liking at 150 yard it should knock a animal off its feet. what is the cost of a ream and dies for a 9x39 set up? I would think that if this could be done You could probably rent out the ream or ream other peoples barrels to offset the cost. I would think that mag would possably be single stack due to the wider bullet. I have been thinking a shell catcher or deflecter would be a good idea also. I have not retrived hardly any of the brass I have shot.
