I have a Super Blackhawk (.41 mag), and I thought that I'd try my hand at closing up the B/C gap by shimming the back of the frame where the cyl makes contact with the frame. This I have done successfully after removing .004" from the front thrust surface of the cyl.
The barrel/cyl gap is now .002" and the end shake is barely noticable when there is a film of oil on the surface.
When it's DRY I can feel a bit of shake, and when the cyl is as far forward as it will go there's about .0005 clearance.
I thought I'd give this a try. I've yet to fire the gun, but if there's any issue I'm expecting it will be due to the additional .004" that was added to the clearance between the breech and the back of the cyl.
At this time the job is clean and sanitary and the cyl spins freely and all the action functions as well as ever.
Any opinions on this?
I'm interested in finding what the tolerances are for breech to rear of cyl face.
I can always undo the job and make it the way it was originally if there end up being ignition issues, due to poor pin/primer indentation.
Thanks in Advance
