This is the only story I have about this and since it happened to ME, I will tell it. I took a Super 38 Colt {at least that is what it and all others of the Colt variety say on the barrel hood}, on a trade with 1K rounds of ammo. Having no use for it, I traded it. Then over a period of a couple of months I shot all the ammo in several different .38 specials. Steel went "ping" and it poked nice holes in cardboard. No damage, just fun. That's my story on this subject.
