Alliant Unique Powder delivers consistent performance across multiple calibers and applications, making it one of the most versatile propellants available to handloaders. This fast-burning powder handles everything from light target loads to full-power defensive rounds with predictable results. The single-base formulation provides clean combustion and stable velocities across temperature ranges.
What Makes This Different
Unique stands apart from other powders through its exceptional versatility across both pistol and shotgun applications. While most powders excel in narrow applications, Unique maintains consistent burn characteristics from .38 Special wadcutters to 12-gauge field loads. The powder's burn rate sits in the optimal range for medium-velocity applications, delivering complete combustion without excessive pressure spikes that plague faster powders.Key Features
- Multi-caliber compatibility from .32 ACP through .45 ACP and 12-gauge to 28-gauge shotshells
- Single-base nitrocellulose formulation for consistent burn rates and clean combustion
- Fast-burning characteristics ideal for short-barreled handguns and standard shotgun barrels
