I may not be doing things right,
But I did a calculation of the density of my compressed pucks.
They came out around 92% compression.
But , when I broke up the pucks , ground them and screened them to each grain size. My grinders of powder came out to 85 to 88 % comparison to granular Goex.
I am not trying to get all my powder to perfectly match up to commercial powder.
I just need to know what the comparison is like so I have an idea on how much volume matches the weight of the factory powders that I have and still use.
