Federal HEVI-Bismuth Features The Federal HEVI-Bismuth shotshell is built around a 9.6 g/cc bismuth pellet that is 22 percent denser than steel which means more retained energy and deeper penetration at the same shot size and velocity. Because the pellets are denser the load delivers higher effective pellet counts than a comparable steel load giving hunters a fuller more lethal pattern on birds. The bismuth alloy is also softer than steel and tungsten making it a safe choice for older barrels and classic double guns that were never built for harder shot. Pellets are alloyed and cast in the USA tying the load to Federal s long domestic manufacturing heritage. The rear-deploying FLITECONTROL FLEX wad is engineered to separate cleanly from the shot column producing tighter more consistent patterns whether the barrel wears a ported or non-ported choke. This consistency matters most in the field where a bird flushing at odd angles demands a pattern the hunter can trust shot after shot. Federal boxes this load at 25 rounds per box for 16 gauge shooters who want a reliable option for upland birds and waterfowl alike making the HEVI-Bismuth line a versatile choice for hunters who carry one gun across multiple game seasons.
