Why is this a big problem with the muzzleloading community ? To me it is a simple concept to understand. F,FF,FFF,FFFF black powder granulations all weights are different if measured by volume . If I measure 60 grains of 1f BP by volume and then weight it on a scale the weight will be different if you measure out 4 F by volume and weight it on a scale there will a difference in weight in the 4F compared to 1F . I said all that to say this; If you are measuring your black powder charge by volume and getting good results then stick to measuring your charge but you could then put your charge on a scale and weigh it . You can, and then you have the true weight of your charge and then you will know what your charge by volume truly weights. If your 60 grains of 2F is 65 grains by volume then you know what your charge can be weighed on your scale. Not a complex idea to wrap your mind around. First use the Volume powder measurer and then there is no reason you can not use your scale to prepare your powder vials of pre shoot powder. Shoot straight Y'all
