Going thru my family horde I found some powder unlabeled, the Oldman swears it's a 50BMG powder (was loading lots of 50BMG for BR). But he is developing a bit of old timers so he can't remember which powder.
I put some samples under the optical measuring machine and measured the sizes vs some known powders...IMR4895 is the first, next H50BMG, last is my mystery powder. 4895 .030 diam .060 long , H50BMG 0.055 x 0.070, powder ? 0.040 x 0.080.
Next is probably a burn test but any advice would be welcome. There is a significant amount and powder isn't cheap.
