Well first off not all powders are equal the are talking about the original black powder substitute call Pyrodex in pellet form. The big problem with that system is that very few muzzleloaders will shoot accurate with that load; long range requires accuracyif you can not hit what you shoot at it don't make any differance what you are using. Yhere are other ways to use that system a lot of the people that use it find a load that the gun will shoot accurate and then by trial and error find where [what yardage ] the markers in the scope will shoot.
