Yep. I think we talked about Lil'gun working well from low pressures (.22 Long Rifle like) to magnum pressures in the .500 S&W. Very versatile powder. Some will say it burns hot. But from my experience, that is only true when O2 is added like from a cylinder gap at moderate to higher pressures.
How dirty was the Lil'gun?
I will say it again. 800X will get tricky sometimes without warning. Watch out.
