Mashburn Cartridges

[truck driver]

While over on the Bullet Forum I ran across a post about the 300 Mashburn Super Magnum. It seems that the poster had sent Mashburn a Rem 721 in 300 H&H to have it rechambered for 300 Mashburn Super Mag. So I sent him an email requesting in foe and this is what he sent and it appears to be from an original Mashburn reloading guide. Click on images to enlarge.

Scotty there is some 7 MSM info here.

Very neat stuff Rodger. Thank you for posting it.

A 270 Mashburn would be another neat cartridge in my opinion. Twisted up correctly I am thinking it would really be a screamer..
