[QUOTE="Dr. Tad Hussein Winslow, post: 1269449, member: 7123"] I picked up some of this stuff yesterday. According to Chuck Hawks, when measured volumetrically, using the T/C U-View measure, "100 grains" of black powder volume of it equals 66.8 grains by weight. If I'm wanting to work up a load for my MLs, starting low and working up for accuracy, and if I want to start with the [I][B]equivalent of[/B][/I] 50 grains of black powder, would I start with "50 grains" as shown volumetrically on my T/C U-View, or "74.9 gr" volumetrically, which would equate to 50 actual grains by weight? In other words, is this black powder "equivalent", equivalent by weight, or equivalent by volume? Anyone know? What about other BP substitutes - are they *generally speaking* equivalent by weight or volume to BP? Thanks. Edit: Evidently, from the velocities gained, the "equivalency standard" (for lack of a better phrase), is much closer to the [I][B]volumetric [/B][/I]measurement, not the weight equivalency (which of course is technically incorrect since 'grains' is a unit of weight measurement): [url]http://www.chuckhawks.com/blackpowder_breakthrough.htm[/url] See, he says he got *roughly* similar velocities from 100 gr goex BP, and 66.8 gr of BH 209 (which is 100 gr volumetrically). So I guess I'll start with "50 grains" volumetrically in my U-View (which will be 33.4 actual grains). It would be "74.9 grains" measured volumetrically if the equivalency existed on a true weight to weight scale. (50 grains= 50 grains=50 grains) [/QUOTE]
