As Hatcher documents in his Book of the Garand, the final chambering decision wasn't a collective one. Every General and other rank seated on the Ordinance Board had long endorsed and recommended the .276 Garand rifle in its 10-rd, clip-fed form for the reasons given in my post you quoted. Only MacArthur's last-minute veto nixed the adoption of the chambering, and JCG was directed to 're-do' the M1 as a clip-fed 30-06 rifle. The 'cost' argument aside, the 'mixed calibers' and supply-lines argument is largely self-rebutting when you consider that during Vietnam the U.S. did exactly that, fielding numerous cartridges for various U.S. weapons, pistols, rifles and machine guns, ranging from the .30 carbine, 5.56, 30-06, 7.62mm, .45acp, .38Special Ed (in S&W revolvers for pilots), and likely several other cartridges I'm forgetting. MacArthur's veto was more about personal ego and less about the economics of the supplying the military services. Last edited by agtman; August 22, 2019 at 05:22 PM. |

It’s not as simple as a better cartridge. There’s lots of cartridges that will disrupt more body tissues than the 5.56. Just need a bigger heavier gun with a bigger cartridge in that takes up more space with no more recoil.
The persistence of the 5.56 is because it does its job in a lightweight controllable compact weapon. The parameters of the new weapon requires it to be “significantly” more powerful in roughly the same weight and package size of the M4... which has proven to be a difficult task. This is evident because it requires a revolutionary weapon that hasn’t been fully proven yet. If they merely wanted a cartridge that was more effective at a longer range, we have plenty of those, no need to reinvent anything. Where energy is involved, there’s no free lunch; you can’t get something for nothing. But I guess math is hard for some people. I don’t buy the train of thought that implies that there is some nefarious government plot to keep a substandard weapon in the military inventories. There’s not a weapon that has made the grade yet, nothing says that the submissions will even pass the testing. I assure you that I’m all in favor of this, but the doubt the timeline will be met. |

It’s not the bullet, it’s the weapon system. If it was bullet alone, we could just give everyone a rifle that shoots a .50bmg and call it good.
You cannot get much of an improvement over the 5.56 and keep the same logistical burden, similar shoot-ability, same ammo load, same weight and in a compact package. There’s lots of cartridges that offer a bit of improvement in terminal performance over 5.56 and still retain the same real estate of an M4, but they’re not earth shattering enough to refit the entire military. This new weapon system aims to do this, what’s in doubt is the timeline. And again, we can’t get a new gun to the troops if it’s never tried. The government tries lots of things that never manifests into reality. Even if something does get through testing, a simple election can end it. 2020-2021 revolutionary new weapon system fielded, when there’s not even a final product as we sit in the last part of 2019? ... not keeping my fingers crossed. |

Cartridge discussion - been a while
It's been a while since I've responded to a military cartridge discussion, so I'll play.
I spent 7 years active duty and have been in the Reserves a little over 3 years. I deployed twice (one was as a QRF and saw no action, however), so I do have some first hand experience. I've always felt the 5.56 was a little under powered to be considered the Army's all-purpose, do everything round. I was in Afghanistan and generally was out in open spaces, so that may explain my bias. I'd like to see: 1. All M4s changed to a 6mm bullet, about 80-85 gr with about a .350 BC fired at about 2900fps. This adds about 200fps and 200 foot lbs of energy at distance. Not a huge increase, but enough to make a difference and also to be better at wind deflection (a real weakness of the 5.56 in my opinion) without adding noticeable recoil or lowering the magazine capacity to much. I think a 6 SPCII would be the ideal cartridge. I'm not a wildcatter, but I think it should be capable of those velocities at that bullet weight. 2. At this point, it would be minimally difficult to change an M4 to 6.8SPC if the mission dictated a more powerful cartridge. Logistics would already be supporting the magazines and bolts. Of course the barrel is different, but still not too hard. 3. Change the 7.62 to a 7mm bullet. I think the 7mm08 would be the perfect cartridge. A little more speed, a little less wind deflection and since the 7.62 round seems to be used mostly when the target is out around 300+ m (but certainly not always, that's just a generalized statement), the higher BC bullet allows the 7mm bullet to keep energy longer, assuming same weight bullet of course. |

6.8spc is a little better performer. The receiver of the M4 hinders using much of anything else without loosing magazine capacity. There’s stuff out there that has advantages and disadvantages, but most wouldn’t be worth the effort and expense just to end up with basically the same rifle.
The new proposed weapons aim to overcome all the shortfalls of the 5.56 (by a rather large margin) without introducing the disadvantages of going back to a larger cartridge. |

Forgot who the barrel-maker was, but this was sometime in the '90s when certain makers were offering M1 barrels chambered for cartridge-derivatives of either the .308 or the 30.06 - e.g., the .270 Winchester, in the case of the latter. In fact, I always thought a Garand in 25-06 might be something interesting to play with, especially if you scoped it - either in M1D 'sniper' form or by running an Ultimak forward rail in place of the rear handguard and mounting a Scout' scope. You could easily tune an M1's gas system to any 25-06 ammo simply by installing Schuster Mfg.'s adjustable gas plug and working things out at the range ... Back to the 7mm-08, ... If I recall correctly, the terminal ballistics and recoil-level of the '08 cartridge is actually pretty close to that of the 276 Pedersen, not to mention also being extremely accurate and flat-shooting. So, if some talented-mind found a way to modified a Garand's action to accept a slightly longer-than-standard M1 clip holding TWO extra rounds of 7mm-08, you'd essentially be back to 'Square One' of the 10-rd, clip-fed semi-auto JCG built for the U.S. military in the mid-1930s. The old is new again. Last edited by agtman; August 24, 2019 at 08:44 AM. |

Or the original submission by FN in 284 to replace the M1 at the end of WW2--that's where we blew it IMO by not adopting it.

The M1 Garand's enbloc clip was obsolete by the mid 1940s. Late in WWII Springfield, Winchester, and Remington were all working on box magazine Garands. The first wave into Kyushu would have had a lot of 20-shooters if they could have gotten one into mass production.
Anthony G. Williams has done a good deal of writing on the subject. History of the "assault rifle" at http://quarryhs.co.uk/Assault.htm Development of the "600 meter round." http://quarryhs.co.uk/Emeric2019.pdf More indexed at http://quarryhs.co.uk/miltech.htm |

The Army is still looking for the "free lunch" cartridge and rifle. They want something that gives them the things they want to eat, and as much as they want to eat without having to pay for it in things they don't want, such as size and weight. They haven't found it yet, and they've been looking a long time.
I doubt they ever will find it, if it even exists, but the only sure thing is that without looking, its unlikely it will just drop in their laps. (and if it did, they'd probably ignore it )

And a lot of the Other Guys were soldiering on with bolt actions.
Enfields on our side, Nagants on the other. I think a problem when you are fighting a "police action" and not going to war. |

If the Army only had access to engineers, scientist, experienced soldiers, and all the resources Bubba has at his disposal the they could have found a 5.56mn Wonder Bullet solving all their problems!! Nobody can beat Bubba... |

If they pay me enough, I might reveal the design of my 6.5 Galactic Armageddon cartridge that uses spent Kryptonite.

It’s a really simple fact, up until now, there wasn’t any gun that could do what the proposed weapon is required to do. Now they have a couple of prototypes for testing. The Army may or may not select one of these samples. And yes, bubba’s bullets, no matter the caliber are always way better than government bullets.

There are lots of things that look good on paper (or PowerPoint) but don't go over as well when turned into real world working models.
What ever happened to that 5.56mm upper with the 20mm programable grenade launcher lower?? It was some time back, the last I heard was they had gotten the prototypes down to 18lbs (still a few pounds above target weight) and the govt was not thrilled about the cost of the grenade rounds, which was reported to be several thousand dollars, each...though that was expected to come down with volume production... As far as I can tell, that idea went away... The days of the military actually doing design work for most things are long past. Which actually fits with the base concept of capitalism, and a free market, as well as cost competition being a benefit to the public. It doesn't always get done that way, but the concept is sound. The army doesn't need to spend resources designing a better mousetrap anymore, they just turn to the private sector and say, "we'll buy a better mousetrap, if it will do A, B, and C. What have you got??" Somebody(s) will come up with something, if there's a chance of making a buck. Always interesting to see if what gets submitted turns out to be something actually better, or just different...

Some cleanup work has been done.
This isn't going to turn into a discussion of why veterans are or aren't, or think they are or aren't, or why others think they are or aren't, superior to citizens.
