Guess its a matter of personal choice. For now. Before too long, that choice will be no more.
Personally, even today, if I had a choice between a JSB and a non toxic pellet of similar performance - I'd pay the premium for the latter. For many of us, the highest price we pay for our hobby is not in the ammo, or even the guns - its in our time. The time we take from our work and our loved ones. So if a pellet should cost a couple pennies more - this will hardly put a dent in anyone's bottom line.
On a more pragmatic note, some of the pellets I pest with end up lost in my backyard, where our egg laying chickens can and do swallow them.
Even when hunting or plinking in the wild, the idea of leaving toxic waste behind is so 70s ... If a raptor eats a game animal with the lead pellet embedded in its rear end, it seriously impacts that raptor's reproduction (which is why in condor country, for instance, it is illegal to hunt even a ground hog with lead ammo).
