HEVI-Shot 15502: 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. The HEVI-Bismuth Waterfowl 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.
