Been shooting My KelTEC 380 P3at with 100 grain lead cast bullet. Sadly not a micro tumble lube bullet. Been using 3.5 grains of Ram Shot True Blue powder. No signs of excessive pressure. Grains used could be a little on the light side.
Now if i could get a True Blue load data for 10MM 180 grain tumble Lube lee bullets, would be a happy shooter.
Ram shot has a load for 40 S&W may try at the high end for the 10mm. See what happens.
