Winchester is using a total jacket on the bullet and has changed the priming compound to one that doesn't have any lead in it. So it's environmentally "clean" - no lead contamination; especially in an indoor range.
Leaves yellow crap all over my .45 Hated it, it may be more environmentally friendly, but it gummed up my usually 99.99999999999% reliable 1911A1 in about 50 rounds. IMHO.

I thought I'd seen it all, until a 22WMR spun a bunny 2 1/4 times in the air!
