Make an old gun out of 'em.
If the barrel is long enough, or you have two or more old barrels, use 'em for forging buttplates, trigger guards, side plates, or hammer 'em flat and use 'em for patchboxes, thimbles, underlugs, sights, or whatever.
Bobby Hoyt can rebore and rifle 'em too.
Check the depth of screw holes and underlugs when you send a barrel out to have rebored. I talked to Bob the other day, and he related how he just blew through screw holes drilled deeper than normal on a TC barrel.
He recommends a minimum of 1/16" of material at the bottom of a dovetail or screw hole, BTW.
