Smokeless H110 is a spherical powder that delivers top velocities with top accuracy in the 44 Magnum, 454 Casull, 475 Linebaugh and the 460 and 500 S&W magnums. Some silhouette shooters claim it is the most accurate 44 powder they have ever used. In addition, H110 is a great 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.
