In my Pro Hunter I shoot 120grs. (by volume) loose T7 in one load,and three Pyrodex pellets,with a 250gr. SW bullet in another load. I use a Nikon BDC scope,and both of the above loads shoot to the same POI. My question is,I prefer the Pyrodex pellet load to the T7 load (because of no crud ring problems with it). What volume of measure could I use with the loose Pyrodex to come up with the same ballistics? Would it be 150grs. ( by volume) of loose pyrodex?Any help would be appreciated. Ron
