Superformance uses ultra progressive propellants that take your favorite SST or GMX bullets to levels of performance that are simply unattainable with conventional propellants. In order to get more velocity in the past shooters have used a brute force approach large charge weights of a slow burning powder in a larger cartridge case. Ultimately this leads to more recoil and muzzle blast.
