Hodgdon Powder offers one of the largest selections of quality smokeless propellants for rifle reloading. These powders are very popular with high power and long-range shooters, varmint hunters, and benchrest shooters.
Hodgdon Spherical Powders are great all-round propellants. These powders give you high performance and consistent charge weights through your powder measure.
Derived from Bruce Hodgdon's infamous 38.0 grains behind a 52 gr bullet in his 22 Wildcat cartridge (now know as the 22-250 Rem). Superb for 220 Swift, 243 Winchester, and 257 Roberts.
