    Been playing with .45 acp shotshells. Factory and handloaded. Now I want to play with the gun a little bit to tighten patterns. My idea is to take my fullsize 1911, replace the factory barrel with a 7" barrel. Before installing said barrel I'm going to back bore it, leaving only 1.5-2" of rifling, and the last 5-5.5" smooth bore. Thought about a complete smooth bore, but I really don't want to apply/pay for a tax stamp. Have any of you guys seen this done? and how did it work? I know back boring on shotguns is pretty common practice, but thats a different animal.

    My other idea, is just replace my barrel with a standard threaded barrel. Leaving the rifling alone, then machine a thread on 2" choke to tighten the pattern.
