That is well and good for you. The guns that I an many others choose to use will not work with steel shot or non lead ammunition. I prefer to hunt birds with an 1850 vintage muzzle loading shot gun and an 1880s black powder shot gun. I do have a modern gun but it was not built for steel shot either. About 2/3 of sporting shot guns in the country will fall into that non=steel category. Muzzle loading rifles and black powder cartridge arms will not accept non lead ammo.
You make your choice and let me make mine.
Well I must admit that I didn’t know there are firearms that can’t handle non-lead ammo.
So, with this new information I must recant my position and support yours.
