Year ago when I started shooting black powder rifles, we always weighed our charges with our reloading scale. It was years before I bought a volume measure. But I stopped weighing after reading this about Pyrodex on Hodgdon site.
Q. Can I weigh charges of Pyrodex for my muzzle loader?
A. There is no advantage to weighing charges of Pyrodex or blackpowder. Because these powders are very inefficient by todays standards, volumetric measurement is the quickest, easiest and most accurate way to measure powder.
I feel the same would be true for all the black powder and black powder substitutes. And so far it has been the same for me. I found no difference in accuracy or point of impact when I started using a volume scale with my Remington. I still shot on average 1" and under groups. I have not experimented with other rifles. I try to be consistent as possible when pouring and closing the measure.
If weighing charges shrunk my groups considerably or eliminated an ocaisional flyer, then I might would weigh charges by weight. But so far I haven't seen or had a reason to go back to the scales. If your looking for the utimate in accuracy and want to elimanate as many varibles as possible, by all means weigh your charges. I don't think a deer will notice the difference in group size.
Just my two pennies,
