Mag pro powder for 300 win mag

[Archer357]

Was able to get an 8 pound jug of Mag Pro powder from Midway USA Today. Anyone have experience with this powder?

I got a little to play with too. I see nosler has it listed pushing a 190 ablr a little harder than Sierra does it's 190mk. Be really curious what you find.

I bought an eight pounder a year or more ago for a 338 Lapua when retumbo was not around although it works I ran into pressure early with lower velocity's and I have not tried it since

It is a short magnum powder but also works good in 300WM. I got better velocities and accuracy with Ramshot Magnum. Magnum also does well in 280AI
