The forcing cone to barrel clearance on my 605 snubbie varies from the right to the left side. On the right I get between 0.004 to 0.006; on the left I get 0.008 to 0.011. The gun shoots well but I noticed that blow by flames are significant when shooting .357 mag loads. i showed the gun to the range gunsmith and he advised me that for a defensive snubbie I should not be concerned that much. I wanted to get some additional feedback from Taurus aficionados before I count it as no big deal. Any advice?
