When Hodgdon H380 Spherical Rifle Powder was originally used by the company founder Bruce Hodgdon it had no name. When one-hole groups were produced from his .22 Caliber Wildcat from a 38.0 charge behind a 52 grain the powder was officially named. Today this powder is one of the top choices for reloading .257 Roberts .220 Swift and other cartridges used for varmint hunting.This smokeless powder offers high velocity and extreme accuracy. To ensure complete customer satisfaction the company puts all of its powders through intense testing and as a result is able to offer a solid guarantee.
