Having issues grouping. 2 chamber will consistently throw right, other 3 will group. Upon inspection, for some reason Taurus decided to stamp a number in the front of the cylinder between the 2 chamber throats. Those 2 throats are very tight, and 1 almost seems to have a bad burr. Has anyone seen this problem? The gun is leaving to go back to Taurus on Friday. I've been prefectly happy with every Taurus I own, including a new 455 snub revolver, if they would not port every thing they make. I don't want to start a war, but just wondering if this is a common problem.
