Hodgdon H4350 Extreme Rifle Powder 8 lb Jug - Temperature Stable

The Hodgdon H4350 Extreme Rifle Powder delivers consistent velocities across extreme temperature ranges, making it the preferred choice for precision shooters and hunters who demand reliability. This temperature-stable propellant maintains performance from -40°F to 140°F, eliminating velocity shifts that plague standard powders. The 8-pound container provides substantial volume for serious reloaders working with medium to large rifle cartridges.

What Makes This Different

H4350 Extreme features Hodgdon's advanced temperature-stable technology that virtually eliminates velocity variations caused by ambient temperature changes. While conventional powders can experience 1.5-2 fps velocity change per degree of temperature, H4350 Extreme reduces this to less than 0.2 fps per degree. The spherical powder design meters consistently through progressive presses and powder measures, delivering charge weights within ±0.1 grain consistency.

Key Features

• Temperature-stable formulation maintains velocity ±20 fps from -40°F to 140°F
• Optimal burn rate for .243 Winchester, .308 Winchester, .30-06 Springfield, and .300 Winchester Magnum
• Spherical powder design flows smoothly through all powder measures
• 8-pound bulk container reduces cost per pound compared to 1-pound bottles
• Copper fouling reducer additive extends barrel cleaning intervals
• Flash suppressant minimizes muzzle flash for low-light shooting
• Lot-to-lot consistency ensures repeatable load development results

Field testing demonstrates H4350's exceptional performance across hunting and competitive shooting applications. Long-range precision shooters rely on its consistent burn characteristics to maintain sub-MOA accuracy at extended distances. The powder's stable pressure curve works effectively in both short and long-barreled rifles, making it suitable for everything from 20-inch hunting rifles to 26-inch target barrels. Weather-resistant properties ensure reliable ignition and consistent performance during temperature extremes encountered in mountain hunting or desert competition environments.
