Hodgdon H322 Extreme Rifle Powder 1lb - Multi-Caliber Smokeless

The Hodgdon H322 Extreme Rifle Powder delivers consistent performance across multiple calibers with temperature-stable formulation. This 1-pound container of spherical powder provides reloaders with reliable ignition and velocity consistency from .222 Remington to .308 Winchester applications.

What Makes This Different

The Extreme series formulation maintains velocity consistency within 1% across temperature ranges from -40°F to 140°F. Unlike standard powders that show significant velocity shifts in extreme conditions, H322 uses temperature-stable chemistry originally developed for military applications. The spherical grain structure meters uniformly through progressive presses and powder measures, reducing charge weight variations to under 0.1 grains.

Key Features

• Temperature-stable Extreme series formulation maintains consistent velocities
• Spherical grain structure for precise metering in all powder measures
• Optimal burn rate for .222 Remington, .223 Remington, and .308 Winchester
• 1-pound sealed canister with moisture-resistant packaging
• Copper fouling reducer additive extends barrel cleaning intervals
• Flash suppressant reduces muzzle signature in low-light conditions
• Lot-to-lot consistency eliminates the need for load workup changes

Bench rest competitors rely on H322 for its exceptional accuracy potential in varmint cartridges, regularly achieving sub-MOA groups at 100 yards. The powder's consistent burn characteristics make it suitable for both bolt-action precision rifles and semi-automatic platforms. Law enforcement agencies specify H322 for duty ammunition due to its reliable ignition in adverse weather conditions and consistent terminal ballistics.

Technical Specs
