I just ran some 44 mag rounds through my Rossi 92 lever gun. I used a 165 lead round nose projectile powered by 6.5 grains of Universal. It generates 10,350 psi. This is from the latest edition of the Lee Precision loading manual. Here's the problem. The cases are exceedingly blackened after firing. I'm wondering if there is insufficient case pressure to fully expand the case in the chamber. So there is a slipstream of gasses backwards from the mouth of the case along the outside of the the brass. While this is possible in theory, I find it hard to believe they would publish a recipe with this built-in fault. Any thoughts?
