I guess I should mention that after getting home, I discovered that the jug had already been opened, and even though it appears to be full, I have suspicions that the contents may or may NOT be H4227. The grains appear to be spherical, and some are a tan color similar to Trail Boss, while others are more black.
So for those with more experience than me, do you think it is actually H4227? or is it a blend of whatever dregs were left in a few other powder jugs?
