Thats all well and good except no-one in the UK has died from eating lead shot meat. If it was really that bad and the risk was that high to ban it, it would be nice to see the evidence to back it because currently, there really isn't any.
We can all argue till we're blue in the face and it won't change anyone's opinions. Lead is bad in certain forms, along with practically anything else in our ecosystem, from excessive heavy metals to exhaust fumes. Its about mitigating risk but except the current risk of lead is frankly minimal as it stands. Vehicle manufacturers put "world saving" emissions limiting devices in place (not that they work mind, it all gets burnt out one way or another but it looks good on paper

). If they want to mitigate said 'risk', only lead free shot game to go in to the commercial food chain, allowing people to still shoot what they like and eat it if they so desire. Boosh, risk gone. That's ultimately what its about, risk to humans (getting over the anti's side of it anyway and wanting to ban shooting altogether).
What we all need to agree on is BASC sold us out to suit their own agenda and it somewhat backfired and that's something people aren't going to get over.
