the surplus ammo is hot-hot if it is tzz headstamp-if you get wcc, rp, or fc its all right-the tzz is isreali made at the nazareth ammo plant and is loaded to around 1100 fps. there was actually a fc on the ammo back in the nineties limiting its daily use to combat and le training because it was battering the pistols from daily use. all the nazareth plant stuff is hot-i have 9mm that pushes 33,500cup and .38spec ball that approaches .357 mag stats.
