I like to shoot my air rifle in the backyard a lot so I’m becoming eco-friendly. I don’t shoot bbs because the ricochet and could hit something other than the target. I shoot pellets exclusively and lead free ones at that. I do not want to handle lead with my bare hands nor have it all over the backyard. Thank GOD for lead free pellets. Now I don’t have to worry about handling dangerous metal or having it in the yard. There are quite a few companies that make lead free pellets, Daisy, Gamo, Crosman, Beeman, Hyper-Velocity, H&N, etc.
Lead free pellets are lighter than lead and so you will get slightly higher velocities. They are as accurate as lead and will not foul the barrel. They are a little more expensive but worth the safety.
