Well, I had a bad case of insomnia (and boredom) last night. I was weighing triple 7 pellets on my Lyman scale when a thought occured. Do different powder measures hold the same amount of powder? So I did an experiment. I used GOEX ffg, which should be close to a 1:1 volume/weight ratio, being real black powder. I had three powder measures: a clear plastic T/C model, a solid brass one by CVA, and the speed loader from Traditions with the graduated markings. The two adjustables were set at 100grains. With each measurer, I poured 100grains worth of powder from my clear T/C flask, and then weighed the charge. I did this ten times for each measurer. Throwing out the highest and lowest readings, I got an average weight for each measurer. The T/C averaged 91.5 grains. The CVA did a bit better at 95.8 grains. The Traditions speed loader averaged in at 102.7 with the most variation in weight between charges. This is probably due to the fact that each charge had to be "eyeballed" to 100grain hash mark. This little experiment makes a strong case, in my mind, for measuring charges by weight. What y'all think?
