Coat Gun

What's the point of having copper coating on lead pellets for a bb gun?

Does the copper coating on the lead pellets prevent it from spreading toxic lead dust or something? Improves shooting?

Way back when they first started making bbs, no-one cared about lead poisoning, so anything with that answer doesn't hold water. If they were worried about that, they would also coat pellets... which they still don't do. The copper does prevent oxidation of the lead, but more so it allows strength for the ball configuration. The ball would be easy to become distorted and therefore would not be as accurate. Also, when it strikes a target, the hard coating tends to keep the shape as a ball to increase penetration. Pellets, on the other hand, don't really need to be coated because they weigh a little more for penetration, have a longer shape for better stabilization and the skirt allows them to be shot at a much higher velocity without distortion. Hope this helps.
