When sighting in a black powder rifle will changing between Pyrodex RS, Triple 7 FFG, and Goex FFG change the point of impact? I know they are FFG but was wondering if it changed, because today I sighted my rifle in with triple 7 FFG and I am almost out, and I have some Pyrodex RS and Goex FFG laying around. Or would it possibly shoot one better than the other. I would think that they all would shoot the same, but im a newbie at these smokepoles
