I took, and maybe I have misunderstood, your use of Zambezi's post to illustrate the point that 'factions' within shooting are happy with an 'I'm alright Jack' approach to be saying that Zambezi (and anyone else making similar arguments, such as myself) was willing to let other shooting factions suffer to preserve his/our own.
You might think he/we are wrong for the points you make, and I can't deny there is some truth to fact that an analogy can be drawn between lead in the food chain for humans and for scavengers. I just considered it unwarranted to suggest that either of us are looking to ignore other shooting groups to preserve our own disciplines.
I completely agree that we should do all we can to slow them down, my fear is that when it comes to lead, unfailing resistance actually plays into their hands.
One of the main current shooter vs anti 'battles' is lead. Ultimately, I have no doubt that the antis will win this battle. There is an unstoppable march amongst legislators throughout the world to make things 'safer' and remove the use of chemicals seen as 'dangerous' to people of the environment. Quite commonly, it seems that dangerousness ifs determined by whether there is a theoretical rather than proven risk. I don't like it but that's the way things are. Increasingly, there is also a determination to remove the ultimate decision on who takes the risk from the individual. Generally. I am also opposed to this.
With that as the background, I simply cannot see that the commonplace use of lead will be allowed to continue indefinitely.
So, my view is that shooting needs to consider how it can use lead for as long as possible. My fear is that we are trying to hold back the tide on lead and if we keep on with that, we will be overwhelmed and slapped with the kind of prohibition that the EU is now proposing. As things stand, that could be soon and the antis will then be free to move onto the next battle. My thinking, which may be wrong, is that a 'phased retreat' will put off the eventual total ban, tie up the antis for longer and give those disciplines which currently have no viable alternatives a chance to get something in place.
