ruger .45acp cylinder to .45AR
Does anyone know how much you would have to machine off the rear of a ruger blackhawk .45 acp cylinder so it would accept .45AR? It shouldn't affect the use of .45acp, due to head spacing on the case mouth.
I was going to look for a Ruger forum, but I thought I would have better luck starting with people that would be more familiar with .45 auto rim.
There was an magazine article about the gun I have, and the author talked about doing this, but I can't remember where I read it.
Any help would be great, thanks
