Hodgdon H322 1lb Gun Powder 1.4C, UN0509

This Extreme series powder has likely won more benchrest matches than all other propellants combined.
H322 provides match-grade accuracy in small- and medium-capacity cartridges like the 223 Remington, 6mm PPC and the 7mm TCU.
As a fine extruded powder, it flows through powder measures with superb accuracy.

Hodgdon H322 is an Extreme-series smokeless rifle powder renowned for its exceptional, match-grade precision in small- and medium-capacity cartridges.
Originally manufactured by Australian Defense Industries (ADI) as AR2219 and packaged by Hodgdon, it has a legendary reputation for winning more benchrest shooting matches than almost any other propellant on the market.
Key Characteristics & Performance
Metering: Because of its small grain size, it flows effortlessly through powder measures with highly consistent drop weights.
Temperature Stability: As a part of the Hodgdon Extreme line, it burns clean and delivers stable pressures and velocities regardless of weather changes (from sub-zero cold to hot summer heat).
Best Common Applications
H322 performs best when paired with lighter projectiles in small-to-medium rifle calibres:.222 Remington & 6mm PPC: Widely regarded as a premier choice for maximum accuracy and tight groups in benchrest and varmint applications..223 Remington / 5.56mm: Performs exceptionally well with lighter bullet weights (e.g., 40-grain to 55-grain variants).
Other Calibres: Frequently utilized for .204 Ruger, 7mm TCU, 7mm BR, .458 SOCOM.
Burn Rate Profile & ComparisonsH322 occupies a relatively fast burn-rate slot for rifle powders.
H322 vs. H335: H322 is a faster-burning extruded powder, making it highly effective for maximizing velocity out of shorter barrels. H335 is a spherical (ball) powder that burns slightly slower.
H322 vs. H4198: H4198 burns even faster than H322. For very light bullets in cartridges like the .222 Rem, H4198 may yield slightly higher velocities, while H322 catches up as bullet weights increase.
