I bought a pound of True Blue a while back to try in everything from 9mm to .45 Colt. Just opened it today. First off, this is the finest ball powder I’ve ever seen. Slightly coarser than powdered graphite.
I dumped 8 grains to start in the .45 Colt and it barely fills 1/4 of the case. Was going to put some 250XTP’s on top of it (I usually shoot 270-SAA’s, but these are for a buddy) and I wanted to get a baseline over my chrony.
Honestly, I’m worried about case fill. Not just for consistency, but, like, a dangerous under-load (either sticking a bullet in the barrel or detonation).
Anybody running True Blue have any thoughts?
