Is it a chambering/caliber issue or a projectile issue. Genuinely curious.

Sure, it's just as fat...if you use the .280/30 version, after the British increased case head diameter (and general case diameter), upping the powder charge in order to try and appease the "more power!" demands of the US Army.

I've always thought the whole idea of a 308 is backwards, since we already had the M14, and it's useful life was...short.
However, now that I've learned that troops pretty much never use automatic fire in their M4's, I have to admit that I'd rather have less ammo and longer range over (controllable) automatic fire. Wasn't the entire point of the 5.56/AR-15 to allow them to carry more ammo, so they could waste more ammo by firing automatically? |

Fuck, do these idiots think Infantry fight in a vacuum with only rifles? View Quote Most people who aren't infantry have no clue how infantry operates, or the concept of having different tools for different tasks.

Weapon only weighed around 10-11lb, depending on model. Range wasn't great (often cited 500-600yd), but that could probably be improved these days. Rounds weigh around 1.5-2.5lb each depending on type and variant. I'm betting the HE version has a lot more bang than any grenade, whether thrown, launched, projected, or fired, ever--though a lot less than a 60mm, obviously, at 5/6 the diameter and 2/3 the weight. India still makes a version (see here) that they claim has almost 1km range--still a lot less than a properly emplaced 60mm from what I'm told, but the whole shebang still weighs under 5kg and setup is nearly instant. Might it actually be handy for smaller-unit (i.e. platoon on down) use, or is it just not worth the effort compared to the 60mm? Seriously curious for answers from folks who have some experience.

In about 1978, or so, we were doing some training for the upcoming ARTEP.
At one of the training stations I was being questioned while the CO (a West Point graduate/captain) and the Battalion Commander (also a West Point graduate AND a Viet Nam veteran) were walking along observing the training. They stopped at the station I was on and listened as I was asked questions and answered them while performing certain functions required at that station. I clearly remember the CO jumping in to correct me about one of my answers. All I could say in response was, "Sir, I don't know about you, but if someone is shooting at me I want the bastard dead, not wounded." The CO got pissed at me. The Battalion Commander smiled, gave me a wink and walked off towards the next training station (which forced the CO to cut the ass chewing session short so he could chase the Bn CO down for more brown nosing). Oh, yeah, we carried M14's, not M16's. Having shot deer with .308's and groundhogs with .223's I know which bullets to use to break big heavy bones and penetrate (shoot clean through) a large animal. And yes, I carry an AR15 with me on road trips these days. With lots of 30 round magazines and lots of ammo. Shoot it till it stops threatening you. I'm prepared for that. If my wife had a .308, instead of an AR15, I'd be taking my GII on road trips instead of the AR15 (for ammo commonality). Same reason I take the CZ 75 Compact on road trips now instead of my .40 S&W P07. She carries a CZ 75 Compact. |

The average Infantryman doesn't need a heavier rifle.
I'm a 240 assistant gunner. If we're taking rounds from distance I'm slamming down a 240 tripod, getting out my binoculars, and my gunner is putting hate easily on target out to 1000m. 1000m hits are pretty easy with a 240L, a tripod, and a good AG calling hits and making adjustments. Even the most basic of light infantry heavy weapons squads can put hits on target out to 1000m. The M4 does fine out to 500. I'm already carrying 400 rounds of belted 7.62 on top of my 210 rounds of 5.56. I don't need it to be any heavier. Well actually, sometimes they stick me with a mossberg 500 like as an AG imma go breach doors. I'd rather have a SCAR and 210 rounds of 308 than carry two long guns Being an E4 sucks |

I didn't listen to the whole thing, but from what I understand the switch has more to do with the AP ability of some new 7.62 round they have developed rather than ballistics or wounding. The army is worried about the Russians and Chinese having body armor that can stop conventional ball and AP ammo.

Hits on target are the most important thing. We have a hard time getting troops to hit shit out at 200 meters. And that's with a super controllable 5.56 rifle with hardly any recoil. Ok, so going with heavier ammo, troops will substantially have less chances to make hits. Because instead of carrying 210 rounds, they got 120, or whatever. Also, it's been said that because of higher velocity, 5.56 is more deadly. That is why pistols make poor weapons to kill. They are way heavier than 5.56 ammo, but have an 80% survival chance. It's because they move way slower than rifle bullets. And 5.56 is screaming at like 3100 fps with the m855a1. And 7.62 NATO is 2,700 fps with a long as 26" barrel.

If combat load is the primary concern, do you believe that 5.56 is the best there is to offer? Honest question. I personally feel that it's close, but not quite perfect in terms of weight/size to power ratio. Though, I'm not quite sure what is better. I'm willing to appreciate the overall efficiency of things like the 6.5 calibers, but the concept of what is needed should be decided first. Is long range accuracy/terminal ballistics the priority or is having more ammo more important? We have a hard time getting troops to hit shit out at 200 meters.

Why would the high brass want to switch to a harder hitting round?
Maybe they foresee fighting China and/or Russia in the future and our potential enemies have created body armor counters to 5.56. Also maybe the Army has better .30 cal rounds in development and have not released the info. Also realize we have not fought a modern army in a long time. It is bold to assume we will always have air superiority in the next war. Calling in for an air strike is meaningless if we don't control the air and the enemy is hitting you with rounds and your 5.56 can't hit them back. I've also learned that armies adjust to the weapons they have. If they have less rounds, they will fire less rounds in suppressive roles. They will aim more if they have to. |

I think we should have both plus an SMG round.
Or a 6.5 in the long mag well, a mid sized mag well for an intermediate cartridge, and a light compact weapon with an effective round in smaller magazines so that specialty solders can carry more loaded magazines and ammunition than infantry with good supply lines and reinforcements.. The ability carry a whole lot of ammo loaded made the m1 carbine very popular. You can carry a good 4 or 6 30 round m-1 carbine sized magazines for 2 AR-15 magazines, so, you get a whole lot more ammo in a space for the same amount of cumbersome. |

A quickly deployed mortar or M203 grenade launcher would have eliminated that threat. But in practice, my particular brigade rarely used these items. We didn't even carry them with us on patrol. My thoughts are that out to 200 yards, use your rifles. Beyond that, a grenade launcher or 60mm is a better tool. With moderate training, when I had an M203, it was routine to put a grenade through a window at 200 yards, which would have been ideal in the outskirts of Baghdad. Perhaps other units used their weapons differently, but we did not. Being fairly fresh out of training, I did not understand why we did not better utilize some of the tools we had access too. Overall, we did ok though. Possibly our fires were limited due to the highly populated urban environment, and instead we used what we were most familiar with - rifles and LMG's. Having been trained as a grenadier for a bit though, there were a number of times when our rifles were not effective, but one or two M203's would have done the trick. |
