STXL
STXL is a high-performance single-base propellant engineered for consistent ignition, clean burning, and reliable pressures across a wide range of field loads. Designed with versatility in mind, STXL is slightly slower than STL and delivers uniform metering and stable performance in varying temperatures, making it an excellent choice for heavier non-toxic loads for hunters, including 12-gauge 3″ 1-1/4-ounce loads and 20-gauge 7/8- to 1-oz loads. STXL’s balanced burn rate supports efficient cycling in semi-automatics while maintaining consistency. Identifier: small (1.1 mm x 1.1 mm x 0.3 mm) gray granular flakes.
