They did.

>>30787265
They did adopt it, they upgraded to 5.56 after realizing the benefits of lighter ammunition

Well, we DID adopt it with the M14, we just realized real quick that it wasn't good for FA in an infantry small arm.

Also, for the kind of fighting that we do these days, volume of fire is superior to the power of what's being fired, at least as far as the difference between intermediate and full size cartridges is concerned. If a soldier can carry half again as much ammo with an only marginally less powerful round, then it's a win.

We still use it in GPMGs.

Lighter boolits=can carry more boolits
More boolits=can shoot more boolits
Shoot more boolits=suppress enemy and take objectives

What is the m240b and what does it shoot

>>30787322
Exactly, 5.56 is an assault weapon round. It would blow apart the animal it would hit. That's why the Army uses it.

>>30787322
Is there a round that was specifically designed just to plink or punch paper?

>>30787342
Yes. Literally dozens if not hundreds of bench rest rounds out there.

>>30787342
22CB and 22 short.

>>30787265
We should have stayed with .280 Bong. Hell, it would have been better if we've gotten the 7.62x45 Czech and renecked it to 7x45. Or just grabbed the parent case of .308 Winchester and made it into 7x45.

The 22lr can probably bounce around and destroy the universe. Shot placement is key.

OP, do you comprehend what NATO on the side of the box means?

But yes, I understand you question (I think). We didn't adopt the round because we need more rounds in the mag that are easier to carry. Most engagements were going on at the 200m-600m range, suitable for the arms chambered in 5.56. The M240 and M14 still use 7.62x51 NATO, which is essentially .308, however.

6.5 is a superior mm
Ballistic coefficient, sectional density.

7mm from a warm case on the other hand.....

>>30787576
^7mm from a WSM case....

>>30787305
The only benefit of the .223 over the .308 is when single element automatic platforms are considered; 308 cannot into assault rifle, recoil mechanics are off

Considering that you can carry twice as many 5.56, keep up high volumes of fire for longer, and still do this... The 5.56 is the superior round for the average grunt.

>>30787372
It's already used widely as anon said, it's just heavy when you compare 200 rounds of 7.62X51 vs 200 rounds of 5.56X45, and the platforms and mags are larger/heavier.

it's a super round with an excellent ballistic coefficient, but the 5.56.45 just fits well for a lighter weight intermediate round and a somewhat lighter weapons system

lug around 180 rounds of 308 sometime in one pocket and 180 of 5.56 in the other, you're going to be drifting to port

I'm wondering why you would shoot a man before throwing them out of a plane?

>>30787265

NATO adopted this round for one reason and one reason only: 7.62 was considered too inhumane to use in war (it can cause some really really nasty internal wounds) so this was the next best thing. Stupid human rights shit anyway, a bullet to the head is still a bullet to the head regardless of calibrate.

>>30788219
300BO is a fine round and all, but it would be tough to integrate them into service alongside rifles that currently use 5.56X45 because when you mix up the ammo bad things can happen.

and in the military this is almost guaranteed to happen

>>30787342

>>30787265
What does "adopt" mean

It's still used for designated marksman rifles like the m110/mk14/m39

Infantry typically doesn't need the range of a full cartridge, rifles that use full cartridges are difficult to control shoulder fired in full auto and burst modes, the weapons that use it are considerably heavier and bulkier with larger receivers and bcgs, standard mags hold less rounds.

>>30788358
anon, stop resisting the future.

>>30788749
6.5 is the future. So are bullpups, stop trying to stick a modern round in your 70 year old grandpa gun.

>>30787698
>308 cannot into assault rifle, recoil mechanics are off
>What is adjustment of gas

>>30788424
Besides that the .300 Blackout was designed for the AR platform as is. We won't adopt a new caliber until we adopt a new family of service rifles and at that point we wouldn't be constrained to the same cartridge length, bolt face, etc.

Besides that 6.8 and 6.5 rounds are better general purpose rounds anyway.

> 6.5 bullpups

I'm dying of laughter.

There a particular reason the 7.62 is mostly used for marksmen? Does it have better ballistics after 300m or something?

We don't really shoot people anymore.
I mean unless it's CQB.

You suppress the enemy, maneuver to a better spot, and suppress them more while the TACP sits back and calls an A10 or a helicopter to come kill the guys you have pinned down.

>>30788962
.223 after 300 yards is basically an icepick after 300 yards, even with based mk262.

.308 has the weight to be effective much further out

>>30788986
Yup.
At range 5.56 can't fragment so it just makes a tiny hole.
.308 carries more energy further and even if it's not at an ideal range, at least it makes a .308 hole instead of a .223

This. ARfags whine about bullet drop with 7.62x39 past 300m yet 5.56 is useless at that range.

All intermediate calibers have trade offs, and all full calibers can do whatever the fuck they want. Just carry the weight and reap the benefits, remember you're not a soldier and your job isn't suppressive fire. If you let a potential target get close enough that you have to suppress it you fucked up. Support is not coming for you in SHTF.
