I loaded up 50 rounds of 9mm with the same Xtreme 124 plated RN bullets and 5.8 grains of Ramshot True Blue powder. True Blue is very very fine and dense, and takes up less than half the cartridge case.
The rounds worked perfectly. The tumbling stopped. The load also worked great in my STI Edge, which requires stout loads to feed well.
True blue is a slowish pistol powder according to the charts.
Can anyone explain to me why a slower powder stopped the problem?
