I have been using copper only since 2017. I personally don't get what the fuss is about.Those who are trying so hard to skip having to use copper / other non toxic ammo , need to go out and shoot a decent amount of deer with some of the best brands of copper . Sure its different but decent copper really does work very well on everything from big Rutting stags down to muntjac and a goodly amount of rabbits. Geese and Duck kill just fine also but the steel shot is a tooth risk , so it certainly needs careful prep
I would like copper to be cheaper , though it would be nice if it costs the same as lead - I feel a lot better my friends and family are not ingesting poison
but I of course support peoples right to make a fuss
