Some are made of standard plastics, while others are bio-degradable.
In airsoft, you can't reuse BBs, whether it's bio-degradable or not. If a BB already being shot from an airsoft gun, it may have beared some cracks (though its invisible with bare eyes) or change it's shape (deteriorate) . If you use it again, you can damage your airsoft gun. Bio-degradable BBs will only decomposing in a specific conditions (i.e leave on a damp/wet soil for days) and will not decomposing in a normal storage conditions.
any bbs will work in any gun i prefer .20 gram crossman whites
yes they are very accurate
All airsoft guns can shoot .12g bbs. However with more powerful guns, heavier bbs are recommended for better accuracy
there are tons of different weights, but never go below .20 gram. .12 gram bbs will break in your gun and destroy it. from there it depends on your gun. The heavier the bb the more accurate it will be, but it will have a slower velocity.
No it's not designed to do it.
no
First, check to see that you have a BB gun, and not a pellet gun. Both pellets and BBs are made in .177 cal. A pellet gun will not shoot BBs (in most cases) If your gun IS a BB gun, you will need a gunsmith to check it for damage, stuck items in the barrel, etc.
