Barnes and other "all copper" bullets will hasten the banning of lead for use in any type of firearm. California has already tried to ban led in rifle shells used to hunt deer. The poor california condor gets lead from unrecovered carcasses of deer, or gut piles, it MIGHT get sick from it! It's a damned buzzard, eater of carrion!
Don't think it could happen here? In europe, it has been tried but failed also. It'll be tried again and succeed.
People jumping on the barnes bandwagon helps the antis think we wouldn't mind loosing the ability to use lead in bullets. But you see, copper is also toxic,(though not AS toxic), so then what do we shoot out of our rifles?
Add to that, nobody needs an all copper bullet to kill anything! With the advent of bonded bullets from Swift, Hornady, and Nosler, bullets will penetrate as deep as needed with reliable expansion and weight retention.
I will NEVER use a barnes bullet in any of my rifles! When lead is banned, I will quit shooting. Hopefully I'll be too old by that time, but it could be next year!
