What difference does it make? It appears he doesn't want to shoot steel, the most cost effective and works just fine for decoying ducks and pats a forest ranges. So we have to assume that he needs soft non-toxics, sxs, older o/u or older pump/semi-auto.
If it is a modern gun is steel safe he would be asking about steel or steel alternatives such as Heavy-13, or TSS or a plethora of other hard non-toxics.
