I have a .33 Siber pistol that shoots beautifully, but, never content, I want a lighter .45 barrel for it.At the Cascade mountain men's show in Monroe, I bought a 9"X7/8"X.45", one-in 22" barrel from Joe William's Gun Works. I have copied an original breech before, so I know what I'm letting myself in for, but do any of you troops have any suggestions or hints that might make the job a little easier? Thanks Guys!
