Keep in mind just how toxic lead is....sometimes, just by shooting your shotgun into the air, causes waterfowl & gamebirds to simply drop out of the sky! They've even found bunnies dead from lead! Heck....military's across the world have known this for sometime. Most have discarded the sword and hacking each other apart, in favor of simply launching lead in the direction of the enemy! Very very toxic stuff! And to top it all off.....last month I was diagnosed with Piscatorial Hemorroidis! The cause? Bobbin-to-hand contact of lead fly tying wire. Very scary:^))))
