My steel frame Pietta 1858 new Army arrived yesterday along with a Pietta owner’s manual and a “Cabelas Instruction Manual for Muzzleloading Rifles, Pistols and Shotguns.” In the Pietta manual, the ball size is listed as .454 and the maximum load is 15 grains of fffg. The Cabalas manual suggests a .451 ball and maximum loads of 35 grains of G-O FFFG or 28 grains of Pyrodex. I hope to use triple seven. I’m puzzled. I guess the Pietta manual should be the one to follow. Just wonder why the differences. Also, no mention is made of cap or nipple sizes. My #11 caps are too big, so I’m assuming the pistol uses #10 caps. This is my first black powder pistol. Any advice on loads, cautions, do’s, don’t’s would be appreciated. Thanks. By the way, the pistol looks and feels great. Can't wait to shoot it.
