I've shot Kent TM, Federal TP, and Bismuth. The tungsten based shots are 100% better than bismuth in my opinion. I duck and goose hunt a lot and am speaking from experience.
Bismuth Cartridge is out of business, Federal won't be producing the Tungsten Polymer loads any longer, and Kent TM is $35 a box for 1 1/4 duck loads. Once I'm out of my stock of shells, which should last me a couple seasons, I'm back to steel and a modern gun I suppose. I just can't afford to spend $3 a shot for the amount of shooting I do in a season.
Kent TM won't last long at those kinds of prices, I think their sales will fall off to the point that they stop producing it. I think the EcoTungsten will be more than $1.50 a shell when it all plays out. I ordered some for a friend in England and was stunned at the tiny bags he got for the amount of money it cost him.
I agree that the days of lead shot for game shooting in the US are numbered. Just heard that the government has made the entire North Slope are of Alaska a non-toxic zone. That's just them starting the process where there is barely anyone to complain. It's coming boys, better get yourselves ready. Anybody young enough to still be shooting in 20 years will see it.
I've shot live pigeons at a club that requires non-toxic shot believe it or not. Their ring faces a river and they started using it to appease the local government and wildlife services.
