STL
STL is a high-performance single-base propellant that fills vital gaps in the powder spectrum. STL is a relatively slow-burning powder for a wide range of field loads in 10ga, 12ga, 16ga, and 20ga. Identifier: small, light-gray granular flakes. The flakes are approximately 1.1 mm x 1.1 mm x 0.3 mm and are very easy to scale, meter, and load. STL is designed to yield high-performance loads with steel shot, copper shot, and other types of non-toxic shot in 12 gauge 1 oz through 1-1/8 oz loads and 20 gauge 7/8 oz loads. Testing shows a similarity to Blue Dot and N350 in terms of burn speed and volumetric density.
