Developed for precision-minded rifle handloaders, this spherical propellant is aimed at varmint cartridges and other small- to medium-caliber applications. It earned its name from a 38.0 grain charge that produced tight groups in a 22-caliber wildcat, and it is noted here for use in cartridges such as the 220 Swift, 243, and 257 Roberts. As with any reloading component, load data should be verified through a reloading manual or the powder manufacturer’s website before use.
