For any reloading application, Hodgdon Powder has the broadest assortment of premium smokeless propellants.
The Hodgdon H380 was designed for use in the 22-250 Remington and quickly gained a reputation for accuracy and great velocity. The H380 is also a great performance with varmint cartridges like the 220 Swift, 243, 257 Roberts, and others.
The Use of Smokeless Powder Should Be Avoided:
Do not exceed the reloader’s guide’s load limits.
Mixing two powders, regardless of type, brand, or source, is never a good idea.
Never use a smokeless powder in place of black powder or a replacement for black powder.
