New barrel blanks are available, reamers are available, and ammo is available. So what's keeping you? Take off the old barrel, insert a newly fitted barrel, reblue, reassemble. Done! Cost wil be somewhere around $200-$250 if you do the work yourself, about $200 more if you pay to have it done.
Never try to educate someone who resists knowledge at all costs.
But what do I know?
