I have a good friend who wants to make a plains pistol. He wants to use it for hunting deer. His barrel will have started its life as a rifle barrel so he knows it will handle a good size charge. So here is the $24,000 question (oops thats $13,300,000,000 now) how long would a barrel have to be to burn 80grns of powder? Is there a source for this info. I think he needs another rifle, but he insist that he wants a medium range (100-150 yards) pistol. :idunno:
