Would it be feasible to re-bore the M4 and M16 to use 7.62mm?
If not, just give our guys more .50cal sniper rifles, just with shorter range scopes.
Garands (not the later development we know and love as the M14) have two big problems - extremely limited magazine capacity and they tell the enemy when you're out of ammo. Not good.
The BAR is a good design, but it's really too heavy to use in anything but the SAW role.
That would be no - the problem is the lower receiver on the AR-15 series rifles. The mag well won't take 7.62x51 rounds, so you have to get a new weapon (the AR-10T) if you want the Armalite in 7.62 NATO.
Bump! ;-)
Ehh... how bout switching to hollowpoints?
Interesting. Have a link or doc's?
AR-10 modified for 3 round burst
The 30 caliber has been doing it right for 104 years. My old 1903 Springfield bolt action with competition sights is my most accurate open sight weapon I have. The M-14 is also an extremely accurate weapon. The Marines know what they are doing.
"Would this be a good time for someone to post a Garand or BAR picture?"
Yes !
Having shot an M-14 on full auto at a machine gun shoot, it is definitely grabbing a tiger by the tail, but I'm guessing the troops would be disciplined and use rapid semi-auto fire. A 30 round mag wouldn't hurt the M-14 either.
That's called the AR-10.
Geneva Conventions of 1924, IIRC...
Yes, it was. The 5.56 round is intended to wound an enemy soldier, not kill him, and to be light enough that a soldier can carry a lot of ammo with him.
The 5.56 was intended to be used in a war of attrition against the might of the Soviet Union. A dead enemy soldier consumes little to no enemy resources (if the enemy is someone like a Western country or the Soviets); a wounded one takes three people out of battle, at a minimum - someone has to haul him back to the aid station or hospital, someone else has to patch him up, and a third person has to nurse him back to health. Not trivial concerns when your anticipated enemy is the Soviet horde.
Thing is, we ended up NOT fighting the Soviet hordes, and instead fought people who *didn't* care about their wounded. Might as well just kill the enemy combatants as all wounding will do is let them continue to try to fight or take you with them.
A hollow point on a 5.56 round .... at least the military round, is not that effective. The existing round is designed so that much of the weight is the rear of the bullet. When combined with a slow twist rate, this creates a situation where the round is designed to tumble. The length of the 5.56 during a tumble is greater than the surface area of a hollow point in the same size round.
See link above. The USMC DMR is based around a recycled M-14.
Yes there is - it's called the Geneva Convention and the signatories have to use 'full metal jacketed' ammunition so that it doesn't 'mushroom' on impact.
The Russians got around that with their 5.54mm round: it has a hollow nose cavity under the jacket. Looks like a solid, ball round, but the thin gilding collapses and it acts like a hollowpoint after impact.
How about 22LR hollow points, no recoil, and you can kill at 100 yards.
Yes, 7.62mm is a 7mm that works fine.
That said, anything we adopt would *HAVE* to become a new NATO standard, and getting the rest of NATO to agree on a new caliber when there's already one that effective in the catalog would be difficult to impossible. It's one of the things stopping 6.8 SPC adoption.
