i recently bought a hunsman bbl. with a stuck breechplug, knowing full well the bore may be bad,. well the jury's still out on the bore (it doesn't look good though), but i'm looking at the possibilities ahead of me. i know there are some outfits that will rebore (a .54 huntsman sounds nice!), or i suppose i could reline or stub the breech. (i have a .458 groove 1 in 24 stainless bbl. that's just singing for use!) i'm entertaining suggestions, with details about the mechanics for applying them!
