The Uberti Remington is a very good revolver for the money. I second the comment about the trigger pull, mine is very smooth as well. Caps - I use RWS 1075's work great, just right in size. DGW says that #11's are what should be used, but CCI 11's are just a little too loose for my liking. One thing I have not found for the Remington is a decent capper that fits it. The Ted Cash that I have is too big to get a cap onto the nipple. I have an in-line sytle capper, it works sometimes but, many of the caps fly off as you pull the capper away. I end up most of the time putting caps on with my fingers - very slow. Ball size - .454 is what is recommended, and they work very well. I have shot .457's through it also with the same performance, just shave a little more lead on seating. I would probably shy away from the .451's they just might be a little too skinny - wouldn't want to risk a chain fire event due to a small or loose ball in the cylinder. Powder charge - 35 or maybe 37 gr. is the max. you can stuff in there, with a felt wad, and still seat the ball. Like all of the revolvers, the closer the ball is to the top of the cylinder when seated, the better the accuracy will be. Whether you use filler or full powder load, get the ball up as high as you can when loading. Out of the box, mine shot about 4 inches left at 25 yrds. The front sight is dovetailed and I was able to knock it over just enough to bring the POA in line. Consistently putting 12 rounds in 4" cicle now with the thing. Like a said, a very good revolver for the money.
