Well, I had an interesting day at the range last week where I shoot quite often, using 3" and 6" Big Burst targets pasted on the back of a B-27 target. I was shooting my .22 Buck Mark Camper for warmup at 7-10 yards and having an accurate day (many several sub 1" to 1.5" groups with just less than 1 second interval). Once warmed up I shifted to shooting DA with the Taurus loaded with factory Blazer Brass .38 Specials. Fired a total of 30 rounds. Once again, nice accuracy (about 2"x2") at 10 yards. Loaded factory Blazer Brass .357 mags, checked that the bullets seated fully and naturally (no burn ring hangups), and started DA shooting again. I was amazed that I was spraying bullets 3-4" left and 3-4" above and below center. I concentrated on my grip and recoil anticipation (I'm a southpaw), reloaded and the groupings got a little better, but not much. Then the cylinder completely hung up with one unfired round remaining. It would not turn it, it would not open. I notified the RO of the situation, told him I was going to continue firing the .22 until the Taurus cooled and then try to open it. He agreed. I fired the .22 for about another 30-45 minutes (100 rounds). The Taurus opened then with a little difficulty. I closed it and opened it several times trying to see what the problem was, but it opened and closed easily after getting it open. I emptied the cylinder, DA dry fired several times, loaded empty .38 and .357 casings and DA dry fired again. Absolutely no problems. I loaded 7 .38s and fired them DA, no problem except they were impacting about 2" to the left and low when previously they had been center grouped. I loaded 7 .357s. The first round impacted in the previous grouping, then the next three impacts started walking further down to the 7:30 position, reaching 6" off center. The last cartridge fired wouldn't advance DA, but did SA. When I pulled the trigger, the barrel went flying downrange and the bullet impact was 20" down at the 7:30 position. I counted my fingers, looked at the shortest snub-nosed pistol ever held, then started laughing. I unloaded the remaining rounds and notified the RO. He called a cease fire, retrieved the barrel, said he'd never seen anything like that, then told me he was selling his Taurus the next day. I had fired a total of 32 .357s. at the point of failure. The gun was purchased in 2003 and has been impeccably maintained. I'll ship it back to Taurus for the second time on their lifetime warranty. The first time I shipped it to them was due to timing issues (it was shaving bullets). Lets see what happens this time.
