This 10-minute video contains a vivid comparison of the power difference between the 5.56mm NATO round and the 7.62 NATO round. It is DRAMATIC...

--any of the .338 or even long-action .30's make the .308 look puny--
That’s Mack from Future Weapons, which is on the Discovery Channel, not the Military Channel. There’s a Discovery Channel “bug” in the corner of the video. I watch it as treadmill fodder.

Hmmm...how many belt-fed automatic weapons and military assault rifles are chambered for .338 Lapua?
Your second equation would be relevant iff we were discussing nuclear weapons.
I’m currently on the 5.56 bandwagon until I can afford an AR-10.
Dump the Mattel.
better of with at least some sort of 7.62 or bigger.....
We used to carry the M-60 machine gun, which fired a 7.62 round. And before that, from WW1 through to Vietnam, the military used the .30/7.62 round for all rifles. So, it looks like it’s “Back to the Future”.
The correct answer to this question is, "not enough."
Historically, when we have to fight the jihadists, we find our individual soldier weaponry lacking in stopping power and effectiveness. The Phillipine Insurrection comes to mind. It brought us into the modern era of .45 ACP, and 30-06 eventually.
I was always a fan of the M-14 and would have preferred that over an M-16. The M-16 was lighter and easier to control in full auto, but it lacks knockdown power and effective range for desert warfare. Most of my duty involved sitting behind sandbags and defending a fixed point, so the weight of the rifle wasn’t a factor. I wanted a cartridge that could reach out 300-400 yards and knock someone down before they could shoot at me.
Yes the .38 revolvers would not stop a hopped up Moro terrorist during the Phillipine insurrection.
I never had any use for McNamara’s M-16, especially with the bumbling way they presented it not in conjunction with Stoners specifications. Anyway his original design was for the AR-10 in .308 a much better weapon...but if combined weight both weapon and ammo and close quarters fighting is the issue, you cant beat an AK in 7.62X39.
As it turned out the M-16 had a longer effective range than what was advertised but the M-14 could definitely reach out farther and do more visible damage. This was with open sights.
The first M-16's we got had many problems. The most common problem I encountered was that the extractor would break the lip on the shell and the brass would remain in the chamber. The shell had to be removed with a cleaning rod down the barrel. I also believed that the gas system leaked on this first batch of rifles.
Future Weapons plays on both and both are have the same ownership.
These are making a nice comeback in Iraq and Afghanistan, and there are some nice lightweight AR type stocks to put them in. It's also my latest addition to the safe.
The M-4 is a lighter -16. Current fielding has most rifles at burst and semi selections only.
My understanding is the AR-15 system is capable of being retro-fitted with any mixture of specialized “uppers” to the trigger system requiring little more than a barrel change and a slip of a fresh magazine to go from 5.56 to 7.62 (or .22, .45, and even 50 caliber!)
And if you want “knockdown” out of a 5.56, lessen the barrel twist. Increase range? Tighten it.
Though to get both range and knockdown, yes, you need a bigger shot.
It must be noted however, that the majority of the fighting over there is door-to-door and range is much less important that weight and volume.
