If you got it in, it's going to be o.k. to shoot it out. Personally, I only have experience with round balls, with the exception of some very bad conicals from a cheap, brass mold back in 1970. The bullet's diameter and composition will decide if it is hard to ram below the chamber mouth. I've read that the Rugers have a little bigger diameter chambers and like a .457 ball. My Pietta likes a .451 ball and a .454 ball works too but is a little harder to ram home. I broke a rammer pin trying to seat .457s in it.
If you are in the experimenting stage with your pistol, I would recommend you buy some .454 swaged round balls. They are much easier to load, since conicals sometimes get cocked to the side a little during loading, which isn't good for accuracy.
Another reason for shooting round balls is that they will always impact lower on target than the heavier conical bullets, which, given most revolver's tendency to shoot high, is a good thing!
