Also. the cylinders of your gun shuld line up perfectly with the barrel. A range rod wiill not tell you this. The only thing that will tell you is to look from the rear,(remove the firing pin on some guns) and see if the same amount of lands on one side as the other. It is amazing how off I have seen Taurus, Ruger, and new Smith guns.
Mike a slug in the front of the barrel, and one pushed all the way through. Most guns made now have a step where the frame meets the barrel,(the tread area.) No gun will shoot well with that kind of problem. It should be returned to the factory. My Smith went back 3 time before they fixed it right. Now I get 1/2 inch groups at 25 yards, all day long. Better than the 3 inch it was getting.
Taurus is having problems with the barrels having even diamensions on both sides of the barrel. My father in law RIP, had a Taurus 44 special that had no rifling on one side of the barrel, and deep rifling on the other. They gave him a new gun.
The lock up of the cylinder should be tested with empty brass in the chambers, as that locks up the extractor in position, and gives a true reading.
there should be only .003 thousanths headspace  on a 44 Magnum, and no more than .006 on the cylinder gap.Tighter is better. Check the cylinder gap with the fired casing in the gun, as that will take up for endshake and give you a true reading.
Check headspace by placing a fired cartidge in the chamber and using a feeler guage, seeing which one fits right.
I hope this works for you guys. I have made a few custom handguns and guaged a few hundred with no unsatified customers yet, so I may have something going.
