Um, the shells are steel, actually. My proof for this is that they stick to magnets and thousands of them are laying on the ground at my rifle range rusting down to the headstamps. The bullet jackets are copper, as I find bits of these jackets as they peel away from the steel core all over the backstops.....
You cannot make a steel jacketed bullet without some sort of teflon or nylon coating as it would blow the rifling out of the barrel (we are not talking sabot rounds, that's a whole different animal). Anyway, I wasn't intending to get technical, I was just pointing out that my rc18t is painted copper (no real copper, that's lexan, j/k), and it's a little bullet (meaning fast).
I also thought the full 7.62 cartridges laying around it looked kind of cool. But that's just me. (oh, the cartridge cases are copper washed to keep them from corroding in the ammo cans, i think they are also laquer coated, too, for moisture proofing).
so, next time I will call my car my "copper colored lexan bodied, speedy projectile car. does that help?
