There are... i think these are non poluting i would assume because they are bio degradible these are .20's
(See The Link Below)
Airsoft bbs are made up of plastic and are 6mm in diameter and are .24 cal, BBs however are metal and are .177 cal (4.5mm)
Type recommended by the maker of the airsoft.
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
no
No, birds do not eat Airsoft BB's. But they are made of non-toxic plastic and would not harm them if they did. They would simply come out the other end in the course of nature.
yes they are very accurate
.25 Airsoft bbs can be good. Their weight is very good for accuracy and helps for a harder hit from the bbs. However, no bb is good if they are not high polish. Companies like Madbull and Matrix make good .25 bbs.
