Hornady Superformance .35Whelen 200GR SP 20Rds

Overview

Superformance uses ultra progressive propellants that take your favoriteSST or GMX bullets to levels of performance that are simply unattainablewith conventional propellants. In order to get more velocity in the past shooters have used a brute force approach large charge weights of a slowburning powder in a larger cartridge case. Ultimately this leads to morerecoil and muzzle blast. The Superformance solution is an elegant approachthat utilizes specialized powders at NORMAL charge weights that impart allusable energy to the bullet reducing the Rocket Nozzle Effect at the muzzlewhile still increasing velocity.
