I have a very old Ideal mold that throws a .456 wad cutter bullet that runs about 195 grains that I load in my Ruger old Army. With as much powder as I can get in and that bullet, it carries better than a round ball out to about 75 yds, where it starts losing stability. I've also loaded a 240 grain 45-70 bullet, but can't get enough powder under it to get much power.
In PA it is illegal to shoot dogs under most circumstances, except that I have had a few chasing my sheep, and the Ruger has done an ok job with just a round ball. Although the larger dog required two shots. In PA cap and ball revolvers are not legal for hunting most animals, the exceptions are 23 caliber and under for small game, and any cap and ball revolver for coyotes and wood chucks.
