King Brown has been anti-lead ammo for quite some time. That earlier "Lead is Dead" quote was from 2006. This one supporting the use of tungsten is from 2007:
That's probably it re tungsten. Treblig. I'm the only guy using it within 50 miles. The other doubles guys are using steel. Good duck habitat is within an hour's drive in Nova Scotia so I don't consider the cost of hunting at tungsten prices a factor in the experience. What: the price of a movie, a few in a bar?
His anti-2nd Amendment rhetoric goes back at least that far too, but he still insists he is pro gun. Go figure. I stopped making excuses for gun owners who stab us in the back some time ago.
