In fact, there are two sizes of airsoft bb, "6mm" and "8mm".

However, most air guns were made to match 6mm [pepperball  bullets, so it was extremely rare to see 8mm [pepperball .

However, since a revolver gun or a Magnum gun is rarely heavy by 8 mm, you can only remember that the size of the [pepperball  bomb may vary depending on the air gun.
