Let me start off my saying I'm new to the pistol reloading scene, loaded my share of bottleneck cartridges and taking on a new venture.

Glock 19
9mm Xtreme HP 147 gn
Mixed brass
Worked up to 3.6gn titegroup

The issue I'm having is only maybe 1 in 10 will cycle this load. I'm not seeing any signs of pressure and the data that I've come across says that this should be my max load. I'm willing to go to a higher charge but figured I'd run it by everyone first...

Could I be having a crimp issue or is my charge to low?

Another thing to add, my brass comes out very sooted...

Thanks!
