Would it make any sense, to take a old TC hawken barrel that is a 45 cal and have it bored out to 50 cal. The old 45 cal barrel I receved from a friend, the bore is rusted pretty bad, I was wondering if it would cost alot to have it bored out to 50 cal and have 1 in 28 twist rifleing put in it. and if so, who does than kinda stuff.
How much would you think I would have to spend ?

Thanks, Steviebiggun
