B&P Dual Bismuth Features The B&P Dual Bismuth load pairs two different shot sizes number 3 and number 4 in a double layer payload designed to deliver dense even patterns no matter the range. Because bismuth is denser and softer than steel the pellets transfer more energy on impact while remaining safe to use in barrels not rated for steel shot. This dual shot size approach extends the shell s effective window keeping pattern density consistent at both closer and longer ranges within the same box. The 1350 fps velocity gives the load enough speed to carry that energy downrange without sacrificing pattern integrity. A special Green Core wad is built into every shell to guarantee optimum performance regardless of temperature and humidity so the load performs the same in cold damp conditions as it does on a dry afternoon. The 2.75 inch high brass hull and 209 primer combination gives reliable consistent ignition shot after shot. Housed in a plastic case and boxed ten rounds to a box this shell is built for hunters chasing birds across a range of field conditions. The B&P Dual Bismuth 12 gauge load is for sale at GrabAGun for upland and waterfowl hunters who want a single shell that performs across variable distances.
