Anyone have any experience with H450? I got hold of some a few years ago and had never opened it. Now that I'm running low on H4831 (with no availability anywhere) I've decided to broaden my horizons.
I was thinking for sure it was surplus 20MM powder, but you might be right. Been awhile. Was Mil surplus for sure just like all the old Hodgdon powders. It was good stuff.It is a ball powder used in 50 BMG and was discontinued years ago. It is the best powder I ever used in my 270 with 140 gr. Amazing accuracy!
Treat it like gold.
