H380 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.
