Hey guys. I have some bp i made and when i weight 80 grains by volume i weighted that on my powder scale and it was 70 grains . Does this seem in the ball park. Not sure ho much BP should weigh verses volume. Shot a bunch of it to day and i was very impressed. Pressing it in a press really makes a big difference verses pressing it by hand. A lot more recoil with the pressed powder and it seemed to work great in my flint lock. Screening my 4f through a 40 mesh and keeping the powder that stayed on a 100 mesh made a huge difference in reliability in the flash pan.
