pellet=no bb's= 6mm plastic not copper.
standard 6mm plastic bbs.
No, metal BB's are generally 4.5mm. If you can confirm that the two caliburs are the same, you can go ahead and try for it. But do not attempt a 4.5mm bullet in a 6mm gun, because the result will be catastrophic for you & your gun. ~Respecktd.
Air Soft guns are not designed to fire Pellets. The shape is just wrong but there are steel BB in the 6mm size avalable. But because they are heaver than plastic they fire or travel slower. If the Air Soft gun is not designed to use them they may actually ruin or break the air gun.
Newton's Law- for every action, there is an equal and opposite reaction. When the bullet is pushed forward out of the barrel, then the gun is pushed back by an equal amount. That is recoil, or "kick". The amount is based on the weight and speed of the bullet, and the weight of the gun. All things being equal, a light bullet kicks less than a heavy bullet, and a heavy gun kicks less than a lighweight gun.
Nope. Plastic BBs are 6mm- about ,24 inches. Metal BBs are smaller- about .177 inches.
If it hits your bare kin it can bruse you.
Recoil is the equal and opposite of the force driving the bullet. A heavier gun is a greater mass to be moved by that recoil.

All airsoft guns fire the 6mm plastic projectile. If you are talking about weight, all will work, but steer from .12 gram BB's. Any others, like the .20, .23, .25, ect, will work fine.
No, as long you don't use metal BB's, any plastic, 6mm airsoft BB's are good to use.
Somwething like this, 223 or 224 diameter bullet is 22 cal. 243 or 6mm is 24 cal 257 is 25 cal 308 is 30 cal and so on. There are some bullet diameters that cross over the caliber lines.
