I'm still hung up on BOSS copper shot not being approved pending USFWS approval of the tester BOSS has or is working on. As I read the USFWS approved non-toxic shot list, pure copper is not approved. This is what is on the USFWS approved list.
Corrosion-inhibited copper | ≥99.9 copper with benzotriazole and thermoplastic fluorescent powder coatings |
Nowhere can I find on the BOSS website that their shot has these coatings. They are only detectable with UV light, which isn't a big deal, but something niggles at me that BOSS is having to develop their own tester and have it approved by USFWS. To me, it isn't worth worrying about. I hunt to enjoy, not look over my shoulder constantly. That said, I am a sucker for new things so I have a 200 BOSS copper shell paper weight until this all gets unwound. There is plenty of Bismuth ammo still on the market and I just found that Winchester is coming out with a new load using TSS18 shot called "Last Call". Spendy at over $4 per round (I shoot 28ga) but even in a good year I don't go through that much ammunition to make cost at that level a deciding factor.
While I'm here, I also wonder why the USFWS approved "copper clad iron" without any corrosion inhibitor? It can be up to 44.1% of the shot mass, so it can be a very think "cladding". Doesn't make sense to this old cowboy.
