Hodgdon H380 Smokeless Powder - 1lb Can - Hodgdon H380 smokeless powder was an unnamed spherical rifle propellant when the late Bruce Hodgdon first used it. When a 38.0-grain charge behind a 52-grain bullet gave one-hole groups from his 22 caliber Wildcat (now called 22-250), he appropriately named the powder H380. H380 is also a superb performer in the 220 Swift, 243, 257 Roberts, and other fine varmint cartridges. See the Hodgdon Annual Manual for recommended uses of this powder.
