First off, welcome to the forum. Next, every 58 Remington that I ever owned needed a .451 ball and only the Ruger Old Army had cylinders large enough to require a .457 ball. The .451 balls always shaved a lead ring and accuracy was always good. My advice would be to get some lubed fiber wads in 44 caliber, such as the Wonder Wads. Measure 20 grains of 3f black powder and pour into the cylinder, followed by a fiber wad. Then seat a .451 round ball on top. Repeat 4 or 5 more times. My most accurate load was 23 grains of 3f Goex. See how that works in your Remington. Go up by one grain at a time in order to see what your revolver "likes".
