I'm not sure about either of those...The barrel chamber on the AMT was so out-of-spec that it 'bulged' the ejected cases...A Series 70 Colt Gold Cup came up and I sold or traded the AMT...

BTW: I just came up with an easy way to custom fit a barrel bushing.

Sounds good! I had a 4-flute adjustable reamer that I used to use...It was tapered as well as adjustable so I could just keep hand reaming until I had a good fit...

I haven't seen it lately...A lot of my tools grew legs...

I was thinking about buying a reamer, but it would be one of those expensive tools I only use once or twice a year. It would probably be cheaper to take it to the machine shop than buying a quality reamer of that size?

It wouldn't take but a few minutes to mock up the Dremel and take a picture if you want to see the setup. It's a bit wobbly, but it works surprisingly well for very light grinding like this. You only need it for the final fit anyway, if you need to remove a lot of material you just use the boring bar first. The only drawback is that grinding on the lathe makes a horrible mess, so you really need to cover the ways and clean/lube everything when you're done.
