Thank you for the advice!Nice looking revolver.
Just an FYI - I shot quite a few rounds of 45 Long Colt out of my 5 inch 460. When I switched over to the 460s, cases had a tendency to stick because of the carbon build up from the Long Colt rounds I had not completely removed. I really had to scrub to remove that, but once I did, I had no more problems. So, if you use Long Colt rounds, make sure to get the cylinder squeaky clean.
I would also suggest that you double up on hearing protection at the range - ear plugs and muffs. When hunting, I just use the ear plugs on a plastic band that I keep around my neck. It would have to be a life or death situation before I would touch off a round without at least some protection.
Hang on and have fun!
