About a dozen years ago I bought a 669 -- 357cal 6" barrel. I can't tell you how many rounds I've put thru it, but it's been an awful lot of fun over the years. About 6 months ago the "forcing cone" split. If it happens to you, you'll know right away.....
Any way I sent it back to Taurus to be fixed, they were great, New barrel, no charge, pretty quick turn around.
However, after running six rounds thru it, I found a pit in the steel, on the crown of the barrel, near the bore, but not in it. Rather than sending it back, I was wondering if anyone sells a 90 degree crown reamer for a .357 cal. Or do you think I should bag it and send it back again?
