National Metallic Bismuth Alloy Shot is great for waterfowl and upland game birds where lead is now banned. Bismuth Shot is a also a great alternative for lead free ballast weight and has a similar density to lead. High quality Bismuth Shot is made using an alloy of ~94% Bismuth and ~6% Tin. Bismuth Shot production utilizes this same alloy while ensuring strict production procedures are followed to provide you with Bismuth Shot comparable to any on the market today.
Note unlike lead or steel Bismuth shot is not round, but will still shoot and pattern excellent! BB's may have small satellites or tails but this actually helps to not generate as much drag in the air similar to a golf ball ie less sticky in the air. No other non-toxic shot performs as similar to lead than Bismuth Shot.
