When you're waking up at zero-dark-thirty and heading out in the chilly morning fog of opening day, you want to give yourself every opportunity for success. You want a shell that delivers maximum force at a price that doesn't force you to take out a second mortgage. HEVI-Shot's new HEVI-Bismuth shells utilize bismuth, which is 22% denser than steel, to deliver more downrange lethality at an affordable price. And, it's safe for older fixed choke and fine classic doubles shotguns. More lethality at longer range than you can get with steel alone, or any HEVI-Shot products except HEVI-X and HEVI-Shot, HEVI-Bismuth Waterfowl comes in every gauge from 10 Gauge to 410 Gauge.
