Optimized Caliber

Here's the video I meant when I heard the guy say "I'm down to 100rds.", which is very common when you press the fight.

Okay, I can hear it there. Except it appears to me it is the M240 gunner who says that, not one of the riflemen.

Even so, you have a good point. I recall reading (on the old forum?) of a Marine veteran of combat in Vietnam who attributed his unit's survival in some battles to the large number of rounds that could be carried with the M16.
