Cost of Bismuth is coming down. So in the future it may well be the shot I pick. It is not there yet. As a reloader with a 10ga. I can create shells with steel that fit any waterfowl hunting situation. They work exceptionally well within the limitations of Steel shot. In the 3" 12ga, If a person shoots within the limitations of a 1 1/4oz 1400fps load of #2 Steel shot. That person will kill lots of birds, as long as they can put the pattern on the bird. I have shot enough high density shot to understand how it performs better at longer range. But with the waterfowl shotgun the goal I have, is to go hunting. When most hunters can hit the local sporting goods store and buy 3, 25 round box's of 3" 1 1/4oz steel shells for less than a 10 round box of high density. Most of us will be shooting the Steel shot and killing birds well enough.
