With an incredibly fast burn rate Hodgdon Extreme H4350 Rifle Powder has been popular among shooters and reloading enthusiasts for years. This has been modified slightly including shortened grains to improve accuracy and ease of metering and new elements introduced that make the powder less sensitive to hot and cold temperatures.

For WSM calibers of .30 7mm .325 and .270 this powder is ideal. However it is also commonly used for .270 Winchester .338 Winchester Magnum .243 Winchester and 6mm Remington as well as other calibers. When it comes to bullets of light to medium weight this powder is outstanding.
