With "Nice Shot" priced at over $45 a pound I don't see it as economical substitute should Bismuth become unavailable. Should Bismuth disappear fromt he market many waterfowlers still using classic doubles may put them away. Worse yet some could resort to being outlaw gunners and return to lead. A box of 1 1/4 ounce Nice Shot loads would run $90 just for the pellets.
