Alliant 300-MP

[hancjamk]

Anybody out there tried 300-MP for 44/357 mag? From what I've read it's an improved 2400.

I have never hear it's an improved 2400 and I highly doubt that's true. 300-MP is new technology and from everything I've heard and read it's a good powder.

I was curious too. On my next powder order, I am going to try a pound and see how it works..

I have been wanting to try this powder in my 357 mag loads and 45 colt ruger only loads. I have held off because I have 16lbs of 2400 and because alliant hasnt done any testing in 45 colt. As soon as I see some test data in 45 colt I think I might give it a try.
