Well, just the other day I was shooting lead round nose .38 out of my revolver- and the wind was blowing aginst me. Talk about lead smoke in the face! I couldn't handle it- I had to stop shooting and get some fresh air. It was then that I decided I was going to switch to that PMC "Green" stuff.
I don't think it would be right to force it on us, but the "green" ammo is a good idea, IMO.
