That's not what I'm saying. Steel works, has for some time. Is there a better alternative, where in the same exact scenario shot A works better than shot B???? Yes. I want to put as many tools in my arsenal as I can. I'm going to shoot more focusing on the types of shot I experienced last year as my first time waterfowling. I have been practicing a ton with my nice new duck call. I am going to scout, find out why the birds are where they are....and I'm going to shoot @ least Kent's Bismuth loads as they are more efficient at doing what I buy shotgun shells to do-put down ducks ethically. Simple physics says that the heavier the shot itself is, the more efficient it is going to be at the same or similar speeds in doing what I need it to do (kill ducks)-assuming I can get it to pattern well.
