After another member E-mailed me about muzzle flash with a EGW comp I have on a 16 inch carbine, I went to an local indoor range to play with a few different types of ammo with the lights turned down. The problem I ran into was with some older ammo from PMC in plain brown box labled 5.56mm BALL M193 with a 81 headstamp. Muzzle flash was very inconsistant. Some rounds produced a very small muzzle flash similar to the Winchester white box I was also shooting, others produced a blinding beach ball size flash that was totally disorienting. There was no external difference in the rounds and they came from the same box. There was no noticeable difference in recoil. Is the rest of this ammo safe to shoot? Also is this due to the age of the ammo or is it possibly an inconsistancy in what type of powder was used in the manufacture? I know true M193 will produce a lot more flash than white box Winchester, but it was very odd how some did and some didn't.
