I'd like to chamber a barrel in .50 Beowulf. Chambering reamers aren't available from the usual sources.
The case is 1.65" long and tapers from .525 at the neck to .535 at the base. With such a small taper, I think it would be reasonable to make a piloted reamer and do the job by hand in the bench vise. This would be attractive since I don't have a lathe with a headstock that can pass the barrel through.
Would a simple D reamer work here?
