The problem with that Chap as taking Semisane's numbers and weights to heart is (and I mean no reflection on the information posted by Semisane) not all volume measure scales are made alike, and not all scales weight the same.

For instance, when I did 100 grains of Goex 2f with my volume scale and then weighed it on my digital scale, I got 103 grains weight. The Triple Se7en gave me 77.1 grains weight.

Granted all of that will be closer then further apart, but make sure you check your own volume measure, and do this each time you change to a new pound of powder. I have found a difference frompound to pound in them as well. Not much mind you, but a difference. If we are doing this for consistancy, then lets be consistant.
