Hodgdon H4350 Extreme Extruded propellant has a well-known burning speed among shooters. Hodgdon has modernized H4350 during that time by shortening the grains for improved metering and making it insensitive to hot/cold temperatures. In the WSM family of calibers, the H4350 is ideal (270, 7mm, 30, 325). H4350 is the industry standard in cartridges such as the 243 Winchester, 6mm Remington, 270 Winchester, 338 Winchester Magnum, and many others. It’s unbeatable for magnums with light to moderate weight bullets!
