Probably only gives you half the energy, though.

That isn't any problem. It's just developing a load your gun likes. No two muzzleloaders shoot exactly the same. Too many variables.
My gun has no limit on powder load. It's made for the PRB, and will shoot the fastest powder charge that's still accurate in it.
