For those of you that are shooting Alliant Black MZ, I have worked out this scale to make it easier. I tested my powder measure with Blackhorn209 and it came within 1.5 grains of the provided info.
Some like to measure their powder on a scale so they can eliminate +/- 1 to 4 grains and shoot more consistent. This really isn't a huge accuracy maker with this powder or even real black powder, but it is your choice and if you prefer to weigh your powder charges for the best consistency, below are the numbers that I came up with.
No tapping on the powder measure was done for the provided powder weight.
Alliant Black MZ
- Powder Volume - Weight Conversion -
V - Volume - W - Weight
50gr V = 41gr W
60gr V = 51gr W
70gr V = 59gr W
80gr V = 66gr W
This is pretty much in tune with the parent maker of this powder, American Pioneer. It weighs closer to Jim Shockey's Gold.
