.350 Mashburn Magnum

Art Mashburn was born on November 6th, 1900 in Springdale, Arkansas. He owned Mashburn Arms and Sporting Goods and became an internationally known gunsmith. He developed several wildcats including the .350 Mashburn Magnum.

The .350 Mashburn Magnum is base on the .375 Holland & Holland magnum cartridge. He changed the case neck to .35 and modified the shoulder to 30°. This allows the .350 Mashburn to propel a .350” dia. 250 gr. bullet at 3,085 fps with 5,256 ft.-lbs. of energy.
