Roughly 300 rounds of 5.56 mm to 180 of 7.62mm.
Thanks for the info... I guess it all depends on the mission you are on for what would be best.
You consume ammunition much faster with an M-16 because you need 2-3 round bursts to have any affect so you need to carry more.
Yeah but it evens out when you consider it takes about three 5.56mm rounds to put down an average attacker compared to about ummmm one for the 7.62x51.
Besides, these days most troops are mounted so the bulk of the ammo is going to be left in the track or Stryker. The 7th ID was light and my old outfit the 9th ID was light, but even we went motorized eventually. I think the 7th and the 9th were decomissioned. I know the 9th was.
