75/15/10 black powder matters
This is the screenshot from the 7mm PRC group, it is not the one I measured so take it for what it is… I recorded my weight on a A&D Fx300i, I check calibration with calibrated weight before use so pretty sure my measurement and this 1.4gn delta are correct. This load measured at -6gn by this guy is insane if it is real, you would assume they have some sort of QC weighting the final weight of each round
