| Didn't know myself what this was, had to ask over at another board (IAA). They think its the XM178 Cartridge 7.62 , ball, over head fire application, turned gliding metal bullet. Will have to get back with the sizes and weights. Not common but not rare either. There is also a tracer aswell (XM179) Thanks for looking wolfgang |

Don't want much dispersion––or wild flyers!––when you're just shooting over barbed wire while guys crawl under it. Same ballistics though, so the sights would still be on. Or in other live-fire practice exercises... I'm vaguely surprised the .mil doesn't have an OF spec for ball anymore. |
