I realize that this isn't a surplus powder, but there doesn't seem to be any Metallic cartidge data out there for it.
I emailed Hodgdon/Winchester a couple times with no reply.
Any thoughts for 45ACP, 40, 9mm? Acoording to the burn chart it falls between Green dot and AA#2.
I thought I would try it grain for grain with Green dot data in the 45, and use my Chronograph to extrapolate some data( large pressure safety margin in 45).
