I weighed out 70 grains of Goex FFg.
When I poured the FFg into an empty .45-70 case, the powder filled the case to the rim -- as full as it could get.
I pressed a 405 grain lead flat point in. I estimate that's about 5/8" of compression. Is that too much compression?
How do I get 70 grains of BP into a .45-70 case?
NOTE: I also tried measuring using a volumetric powder measure. The "70" charge weighed 69.9 grains.
