12 Gauge 3″ Magnum BSC Copper Shot #4 1 3/8/oz

THIS IS SOLID COPPER SHOT TOTALLY LEAD FREE, Introducing Ballistic Saturn Copper™ (BSC™) shot —revolutionizing the industry with a commitment to quality and product innovation. U.S. Patent 8,122,832 B1 | Other patent(s) pending. Key Features: Patented Saturn Shape: Utilizing the unique and patented Saturn design, which has been proven by years of field applications. Ballistic Saturn Copper™ is a duplex pellet combination specifically designed for superior ballistic performance. Premium Material Blend: BSC™ features a specialized 50/50 blend of CIC passivated copper and tin-electroplated copper, which alters the friction behavior of the shot load by modifying surface shear and adherence properties. Tin-on-copper friction is lower than copper-on-copper friction, which is one reason why copper and tin are used in mechanical contact parts. Both types of pellets are 99.9% copper with identical average weight and a density of 8.9g/cc. The surface properties of copper and tin exhibit a complementary relationship with the friction, compression, and impact forces between the projectiles. When paired together, copper and tin surfaces exhibit a lower friction coefficient.  Compatibility: Copper is softer than steel, thus more suitable for older firearms and fixed chokes. Copper pellets are not prone to fragmentation. Each pellet is engineered and manufactured to precise tolerances and uniformity, setting a new production standard in the shot market. Improved Performance: BSC exhibits extremely impressive patterning results and the Saturn design produces enhanced wound channels and greater energy transfer to the target. .
