DOD ditching 7.62 NATO (.308) and 5.56 NATO (.223) and going to...

[midnight rambler]

...6.5 Creedmore across the board for all light small arms including belt fed SAWs so they only have one caliber to keep on hand.

[vacuum]

From what I'm reading, they are only going to 6.5 creedmoor for snipers at this point.

The next gen weapon hasn't been specified yet, other than it will likely be chambered in the 6 to 6.8 mm range.

[midnight rambler]

A buddy is in the Guard (having previously been in the Army) and the info in the OP is what he's been advised of.

[Horn]

Never shot a creedmor, but if its anything like 6.5x55 swedish.

That was the best cartridge/projectile I ever had the pleasure of firing.

Understand the whys , mostly because of weight = more bang for the buck. Being hit by a 7.62 NATO (.308) is no laughing matter. But I can understand if the ballistic sorta reasons, (still boils down to weight + bang) = general firepower. One holy grail has been range and accuracy (depending on the very least the barrel finish and temper. + a tad other issues . (shoot match and u will understand, grin)

.308 ballistically is a great round, sorta a multi tool as ammo goes, except its weight. Have taken many many 30-06 brass and turned them by swagging them down to .308, then cut the neck to length, because ballistically the end result is near the same performance range wise if not flatter trajectory.

Still boils down to weight along with newer powders but unless higher velocity's are achieved grain for grain, less weight = less energy delivered down rang and less punch and terminal foot pounds muzzle energy, depending on the ballistic coefficient + speed. = range and end terminal energy delivered to the ones u want to kill.

Why in the fuck we still keep the .50 cal around? (10,000 to 15,000 foot pounds given to that loving pill sent to they that u want to say I love u) Lmfao.. (because that sob is amazing and also amazing range)

Bang for the buck + weight , same reason why the 30-06 was dumped in modern times..

Prove me wrong....... wish I was still shooting and could get my hands on that newer round, and afford proper barrel, actions shit for example a rifle that can handle a 30-06 can handle a .308 if the action is adapted for the shorter round.. fact. just change the barrel.

(old wildcatter, little old me, back when I could afford it) Still love the now old 7mm-08 , before Remington before it got the Remington last name. I was shooting that round in the very early 80's reforming 30-06 brass and trimming brass to make those sobs, still have my old die's (heavy hitting + accurate round) But shorter and tad less powder needed.

I could go on...

Have a fine day guys....

Me... The Dog with dander.....lmfao... http://gold-silver.us/forum/attachment.php?attachmentid=9893&stc=1&d=1532469652

5.56 is a good round also, was developed for the same reason, more bang for the weight which doomed even the 7.62 for ground pounders..

For the real shooter, spotters in computation looking over the shooters shoulders, depending on the atmosphere and humidity, can see the flight path of the bullet as it goes down range. .....Fucking fact .. Like wise, if the light is right and angle, U can be off the side will be able to see the flight of that tiny lead pill, Amazing. I have had spotters before the dam round hit the target tell me I missed and give a clue ether high or low... U can see the air being torn apart with a black dot in the center, (not the real bullet, two fucking small to see at the ranges I used to shoot, but still sometimes sumthing can be seen) Think heat waves in hot weather......In my computation I had to read those waves to judge where to hold to hit the dam target..

Self to self, shut up Charles,

Again have fun guys..

I know nothing..

The Swiss figured it out, 6.5 is the sweet spot.

Thanks for the memory's old Dog!

6.5x55mm Swedish MauserThe one that started it all. The 6.5x55mm Swedish Mauser (http://www.luckygunner.com/rifle/6.5x55mm-se-ammo#rid=ppt) is nearly 125 years old and is still going strong. Known for its low recoil and pinpoint accuracy, this round has really been able to stand out in competitive shooting and on mid-sized hunting trips.
https://www.pewpewtactical.com/wp-content/uploads/2017/08/Swedish-Mausers-on-a-clip-e1503537739340.jpgSwedish Mausers on a clipEven in today’s terms, the Swedish Mauser is more than a functional cartridge – it’s downright lethal. It’s been featured in a variety of hunting rifles, including the Remington 700 (https://www.pewpewtactical.com/remington-700-buyers-guide/) and the Winchester Model 70, and has been a favorite for deer, elk, reindeer, and moose hunts.
6.5mm GrendelThe 6.5mm Grendel (http://www.luckygunner.com/rifle/6.5mm-grendel-ammo#rid=ppt) is an AR-15 round that’s been around for almost 15 years now. It’s designed with the intention of being more accurate than its .223 counterpart, while also being able to boost power without adding any real recoil.

No thank u...

Be well

[Dogman]

sum of the hottest round were in the 6 range, but bore erosion was huge, mostly in the throat along with other issues

Think 22-250 or ..

Same hot rounds that do amazing things but barrels have huge short lifetimes, back in the day. Flat shooting amazing range, but due to the barrels short unless replaced life time overall. I still own a die or two of variants of that caliber. Never had a good answer, that really satisfied my want to know ;D

Throat erosion was common back in the day. then accuracy went to holy hell...Lmfao..

I know nothing, Love being an idiot here..Considering the lesser idiots here slinging shit...

;D

I might have a clue...

Peace !

Hint: the .308 is the same dam case other than minor lengths and caliber of 7mm-08 take that and

smoke those facts, parent case is the 30-06.

Rifles chambered 30-06 can shoot both rounds, in a pinch, tho highly not recommended at all,

Truly.... I seen actions blowing up, worse case.

I had a Winchester Mod. 70 Featherweight that on occassion I fired the 7.62 NATO cartridge. But they are not exactly the same dimensions and it is dangerous to fire the .308 Win in a 7.62 NATO rifle.

Difference Between 7.62 NATO and .308 Winchester

7.62 NATO vs .308 Winchester
The 7.62 NATO and .308 Winchester rounds are very close to identical with each that many people think that they can be used interchangeably. The main difference between the 7.62 NATO and .308 Winchester rounds is with which rifles you can use them. If you have a modern rifle that shoots .308 Winchester rounds, then it is very likely that you can shoot 7.62 NATO rounds. If you have an old rifle meant to shoot 7.62 NATO rounds, then you should never use .308 Winchester rounds.


The reason why (http://www.differencebetween.net/language/words-language/difference-between-how-come-and-why/) you should never use .308 Winchester rounds in a rifle meant to fire 7.62 NATO rounds is the size of the chamber. The rounds of a .308 Winchester will be too loose (http://www.differencebetween.net/language/words-language/difference-between-loose-and-lose/) inside a 7.62 NATO, This can have terrible results when you fire the round. As the powder detonates, the shell might stretch too much, causing it to rupture and explode. A round exploding in the chamber is a bad situation by all accounts and you will probably ruin your rifle as well as injure yourself. The 7.62 NATO rifles were meant to take military spec bullets that have much thicker shells. Not only does the thicker material make the shell stronger, it also reduces the space inside for the powder.


But if you turn the tables and put a 7.62 NATO round in a .308 Winchester rifle, you should have no problem except for a minor hitch when it comes to the length. Some 7.62 NATO rounds may not fit into the .308 Winchester chamber simply because it is too long. This happens very rarely and many people have used 7.62 NATO rounds for years and have not encountered this problem. This is probably a problem with older rounds and rifles.


If you have a .308 Winchester rifle, you can use either of the two rounds just as both are perfectly usable. But if you own a 7.62 NATO rifle, it is much better if you just stick with the 7.62 NATO rounds. There’s no reason to compromise safety by using the .308 Winchester rounds.


Summary:


You can shoot 7.62 NATO cartridges in a .308 Winchester rifle but not the other way around
7.62 NATO rifles may have too much headspace for .308 Winchester rounds
Some 7.62 NATO rounds may be too long to fit in a .308 Winchester rifle

Had to log in again just for ur post, very long day... once I saw ur post u older than me , but not much overall .

Yes there is a diff, but minor , for peak performance no, but safe to fire, yes.The chamber and round need to perfically (sp) match.
, ,

Tho due to a thing called fire forming , once fired in the larger chamber,, the brass will need to be reformed for another gun, to match the chamber of that gun , which normal dies will handle. the secret for accurate shooting is have a chamber and round that tightly fits, but not so tightly that the case cannot be extracted. (despite the barrel)

Note: due to tooling chambers change from gun to gun, no chamber is the same, overall. for true performance as the best the particular gun is capable of doing , the ammo should be tuned to that gun. Fact! ;D

Along with the action and very importance the barrel. But who am I , ? ;D

rare thing, in the gun will hold , off the production line, but again rare thing is to do sub MOA bug holes , true fact here...Hoot. \\ hell i am tired, normal total sleep total 4 hours in 24 if very lucky... Night guys. good ones and the shitholes here..

Shutting down, hoping for rest, (with a wake up)

Nite monty .

Added note:

The 6mm is a great round, flat shooting but unless sump thing changed throat erosion and barrel wear is or was very high. But the same can be said for any hot cal. If the military, make it so barrel changes are quick, and no brainier + the head spacing is correct, great for spray and pray...lmao...

[Horn]

No thank u...

Be well

Dogman's barrel and a bore, worn out.

The recoil alone is enough reason to leave the other calibers in the dirt. who cares if your bore is worn when most military have hard caps well under anyways?

I posted that for people that may not realize that there is possibilty of headspace problems when firing a .308 Win in a 7.62 NATO rifle. Yes, I used to fireform brass when I was reloading many years ago.

This .308/7.62 NATO discussion reminded me of a time whe we were young boys an old rancher had a Winchester rifle he loaned me to hunt deer with. He said it was a .303 British. The old guy fired a round through it, fire and sparks flew everywhere. When I got the rifle my dad and the ranchhands all looked at it and determined it was a 30-40 Krag.

Moral of the story, don’t be interchanging amunition if you don’t know what the hell you are doing.

[Dogman]

Yup ! to all.

[old steel]

Isn't the army's new stand sniper rifle chambered in .300wm?
