I just ended up with a Taurus 669. There are a bunch of bullets jammed in the barrel, and the cylinder end is buggered up. I'm going to set back the barrel one turn to try to clean it all up. Can't figure out what the barrel pitch is. Seems to be 13.5 mm. Brownells, Midway, and a few other places I called didn't know and did not offer taps of dies. Anyone know what the thread is and where to buy a tap and die?
thanks,
