colt trooper cylinder alignment
Hey guys I have a colt trooper mark III .357 that is shaving bullets. Has to be a problem with cylinder alignment. Right? Are there any quick fixes or should I look for another cylinder and swing arm? Thanks.

I believe the problem is that your revolver is out of time. This means that the hand is worn and does not push the cyl quite far enough to align with the barrel. Shooting quickly double action will cause the cyl to rotate in line with the barrel. Try cocking the pistol slowly and see if the cyl can be rotated a little further after the hammer cocks. The solution is to stretch or replace the hand. It can be stretched by peening but this causes the other internal parts to not work correctly so they will have to be filed down or whatever to make them work together. I learned this the hard way so I suggest you take it to a gunsmith who is very famiiar with revolvers. If peening does not stretch the hand enough, a new hand will have to be fitted. 0 -
Checking the timing would be a good idea. I have also found the forcing cone on the rear of the barrel to be at fault in a number of cases. You would need to have it polished if you can see or feel turn marks in the cone area.This is not a big job but I would suggest having a gunsmith handle it as he may able to help you even more if your using lead bullets.

Check the forcing cone as it may not have very much of a bevel. With the gun unloaded cock it and use a light to look down the barrel and see if the cyl is aligned with the barrel. Usually if the cyl pawl is indexed firmly into the notch with a little play you should be ok and then just open up the forcing cone a little. You can do this yourself if your carefull with a reamer or a ball stone the same size as the bevel on a dremmel slowed down with a voltage reducer or simply chucked up in a slower drill motor.You only have to take off a little so do not get crazy. If your comfortable with this go ahead and do it. Brownells makes a rod that slides down the barrel into the cyl to check alignment and this should be the first thing you do. 0 -
Check the gap between the barrel and the face of the cylinder with a feeler gauge. I can't remember Colt's specs but you can check online for those. On a Dan Wesson .357 it would be .006. 0 -
You've been given good advice, I've owned 4 Colt Troopers over the years, of that four, one was a pretty good pistol. The others had timing, or forcing cone problems.

Are you firing it single action or double action? Alot of people fire fire DA pistols SA for target practice. I'm not sure if ALL Colt pistols do this,but I know some do. When it cocks, it moves the cylinder to ALMOST aligned position. Then when the trigger breaks, it nudges it to the aligned and locked position.
But on older, worn examples, sometimes the little nudge doesn't work as well as it should. Particularly in SA mode. I've got an old Army Special that does this. You have watch VERY closely to notice it.0
