I know someone said that we had lead before batteries and we will have it after. I agree. We will have it but my question is, what will be the cost? If they don't have those cheap options for lead, they will have to buy the more expensive option to produce. IMO, we are on track for a forced switch over to copper. Partially because of the raptor and carrion issue but the other issue might be the cost lead in the future. Copper is getting more expensive with electric cars, "renewable energies", home building, and more. So maybe it gets expensive all around.
The Pittman Robertson fund is an interesting point, if they make it too expensive to target shoot, hunting and conservation across the board would be in dire straits.
I am one of those guys who has switched over his hunting stuff for monolithic bullets and nontox shot. Are they just as effective? Yes. You just need to know the situation they are effective in. Similar to lead bullets, there are situations each type of bullet is effective. The reason I did switch was partially curiosity and in some cases, it is the only option.
I do still use lead for target and clays but that is it. I am one of those people buying cheap and stacking deep. I did it before the pandemic and I will have powder, primer, brass, and bullets for years but now I am stacking the copper and non-tox deep for future use too. Hopefully they will have a purpose in the future
