I had been picking up Used BP rifles from local gun shops and Pawn Shops for around $150 to $250.
Some were European made and some were TC's mostly crudely finished Kits.
I didn't care, because I was going to rebuild them anyway.
So far, I have gotten really lucky, and all of the barrels cleaned up real nice.
But if one had a bad barrel, I would Pay Less and I would probably just send it to Hoyt to be rebored, or just use the good parts on something else.
