RE: Paper Patch Bullet for 44-77
I have 2 of those GM barrels,17 twist, they are the older cut rifled barrels and I have checked them with gage pins. I am told that they are .438- .446 now that they hone them. They are .436-.446, one is on a pedersoli sharps and the other is a blank. Being .005 deep I don't use paper patch, but with a custom mould it shoots lights out with greasers. The sharps was built by Jerry Vanwey at Raton.
