Hey guys, here's the latest on my predicament. I was looking for a roller to use as a parts gun, and bid on one at Gunbroker. Got it. It has the same octagonal area around the chamber that mine has, with a very good bore
Then the gunsmith called and proposed a reline, and has a line on a .43 reamer.
So that is what I'm gonna do. If I can keep the original barrel (which is pretty near excellent) I'll be happy.
So now I'll have 2 rollers.
I may take down the new one and do a restoration, maybe not. We'll see.
On that weird idea, another fella at e-gunparts suggested using Steel Bed, available at Brownell's. I didn't have the guts to try that myself, but some folks are making it work.
