Hey all, I've got a couple of open cans of Hogdon Triple 7 powder that are about 2.5 yrs old at this point. Does anyone know if the efficacy of the powder is reduced over time? I'd like to go to the range and shoot the muzzleloader a bit more with the intention of hunting with it more. Not sure if I should get new powder of if I can rely on the older powder. Thanks for the help.
