I am currently running a 180 Winchester HP over a 8ish charge of BE-86. Shoots good and functions fine.

I find this BE-86 to be a bit hotter than the book says. At least for me.
I loaded some 9MM stuff with it and it was very stiff and I was 10% off max.

Same for the 10MM

If it jams force it! If it breaks it needed replacing anyway.
