Just got an e-mail from them, some of their new ammo is tin core. They seem to be promoting alot of lead free ammo.

I dunno if it is to get away from the lead comodity market some, to help maintain stable prices. Or they feel there will be more EPA/DCNR regulations comming from the Obama Administration.

You'll see it goes from steel target shotgun to 22lr. But not all their new stuff to be tin-cored.
