diameter, bore or groove?
BS Sr.,
Well said! No way can I prove it but the indirect evidence like-- amount of leading, fouling and basic accuracy tends to support exactly what you posted.
For soft lead, paper patched bullet final diameter over black powder in single shot... I've settled on somewhere between bore and groove diameter with bullet seated out so paper patching engraves into rifling.
Black Prince,
Don't care what anyone says--- I like your tastes in wogs and wifles. You should've left the pic up of your Highwall! :mrgreen: Here's one of my favorite lookers.
