Well, Hot Dog! I finally got this thing licked! The only thing left is to "pull the trigger". The Clymer 45 ACP barrel chamber reamer did it's job, although if it is not precisely the way it should be I won't know, because I am not a gunsmith(woops). Regardless, the 460 Rowland round fits just the same way that the 45 ACP did before I started cutting. So, here's wishing me luck when I go to the range.
