The IMR Hi-Skor 800-X burns slower than the 700-X and was designed to be as flexible as possible. There are several tiny gauges, targets, and 12ga field loads. In addition, this powder is employed in stronger handgun loads. This coarse-grained flake powder performs well in heavy field loads ranging from 10 gauge to 28 gauge. In handgun cartridges such as the 10mm auto and 44 Remington Magnum, 800-X performs admirably. Top precision results from excellent velocity and homogeneity.
