H110 is the spherical powder that screams "no wimps, please!" It delivers top velocities with top accuracy in the 44 Magnum, 454 Casull, 475 Linebaugh and the 460 and 500 S&W magnums. Silhouette shooters claim it is the most accurate 44 powder they have ever used. In addition, H110 is "the" choice for 410 Bore shotgun, especially among top competitive skeet and sporting clays shooters. It handles all 2 1/2", 1/2 oz. loads, as well as all 11/16 oz. loads for the 3" version.
