On the contrary, I believe that you are being naïve.
It's your opinion that not only the Eu want a ban on lead or shooting. No major political party in the UK admits to being anti-shooting. The Labour party obviously is, but it is notable that they didn't ban lead last time they were in when the science and the arguments were precisely the same as now. The Green party is insignificant in this country and outside Brighton is of very little relevance to anybody. It is also bonkers.
What happens when WJ take a crack at lead? Well, nothing. Because their are legal activists, they can only campaign in areas where they see a difference between current practice and their interpretation of the law. There is no law that potentially prevents the use of lead shot. You won't like it, but I would also point out that all of their activities to date have relied on EU legislation.
The shooting organisations are indeed being proactive.....in moving towards a goal of no more shooting.
Let's suppose this is a step towards a situation that you think the antis will tolerate. What is the final destination? Where is the sustainable situation where suddenly antis and communists, magically become pro-shooting or neutral? It doesn't exist! It's wilful naivete (at best) to pretend there's a compromise solution. There is no point taking any step to appease these people because they are only appeased when you have become a vegan, have no guns or implements more dangerous than a drinking straw and have signed up to a neo-communist totalitarian state....if they haven't decided you're a class enemy or intelligent and need to be killed. You probably think this sounds very over the top....it is, but it precisely mirrors what these people have actually been on record saying they want.
Lead shot is dealt with. What next? Oh, NOx emissions from the powder. OK, we go along with that proactively too. Now we have guns that we can't fire adequate shot through, but it doesn't matter because they won't go bang anyway, and we won't be allowed to have them.
To finish on a serious note, where exactly do you imagine a "proactive" solution which will satisfy the great unwashed to lie?
