It's a voluntary transition away from lead shot and single use plastics that everyone that shoots can choose to get involved in whether or not they are members of any organisation. For example, BASC sometimes issues a call for voluntary restraint on the shooting of waterfowl during prolonged periods of severe winter weather. You might not be a member of BASC but you might act on it? Woodcock and brown hare also spring to mind. The same for codes of practice.
As regards policy work - BASC's argument against Health and Safety Executive proposals to ban lead shot for live quarry shooting is that the voluntary move away from lead shot for live quarry shooting is reducing the risk to a wide range of bird species in terrestrial habitats. And that the shooting sector must be allowed time to develop non-lead shotgun ammunition due to a world shortage of components and the need for manufacturers and assemblers to source new machinery to produce lead shot alternatives and biodegradable wads for all shotgun calibers.
Hope that helps provide some wider context - but bottom line is that its your choice whether to move away from using lead shot for live quarry shooting for the sake of the birds picking up the lead shot and suffering ill effects from that.
Conor - i like much of what you say - but to try and pull on heart strings " the sake of birds picking up the lead and suffering ill effects from that " is wrong - how do we know the alternatives given time are not to be worse ?
The opposite argument of wounding with steel is
