Re: 6.8 Remington SPC

DPMS , Armalite and Knight all build an AR type rifle that uses the larger cases up and including the 300WSM , I don't have my AR-10 anymopre to compare parts but if anything in interchangable it might be the pins and maybe the trigger , other than that the gun is a good deal bigger in every aspect , the AR-10 , sr-25 and what ever DPMS is calling theirs look like an AR-15 on steroids , probably 50% larger all the way around. It would take a half a role od duct tape to get an AR-15 mag to stay in the well of a SR-25 , the SR-25 and its cousins use a modified M1A magizine.
Not saying that these guns ar bad just big and heavy

Re: 6.8 Remington SPC

Due to the Geneva Convention/Haague Treaty, summot like that expanding bullets are not sanctioned for ue by Military. Police can use what they wany. I know the Irish police use (among others ) 155 grain Laupa factory ammo with the lapua mega bullet.
The 6.8 SPC is re inventing the intermediate cartridge wheel. If NATO had adopted the intermediate 280 British (7x44) back in 1953 instead of the 7.62x51 then we would have had a capable cartridge that fits all of the requirements. extended range/knock down power over the 5.56 and less weight and bulk than the 308 win. but thats all history..

Re: 6.8 Remington SPC

Since this is somewere near my alley I'll try to set most straight.

The M16/M4 series of today are durable, reliable, and accurate enough for there purpose. The 5.56 variety is also extremly lethal as long as you understand its limitations. With M855 or M193, impact velicity must be 2700fps or more for reliable fragmentation. What that gives you is about 240m for the 20in barreled M16, and about 140-160m for the 16in M4. Both are well withen almost all engagments.
Now, with the 77gr OTM round its a whole different ballgame. Pretty much if you can see it through a CC0, you can kill it.

On the 6.8 SPC, the group that designed it are very knoweldgeable. Soldiers from 5th Group, the AMU and a couple indipendent terminal ballistic guys are what created this.

Several cases were tested for maximum feeding reliability. All calibers from .24-.30 were tested for the best terminal and external ballistics.
After all was said and done, the one that was the best OVERALL, from CQC distance to 500m, the most reliable without having to recreate the weapon system, and controllable in full-auto fire was the 6.8SPC with the 115gr Hornady OTM.


Hope that helps. [img]images/icons/smile.gif[/img]

Re: 6.8 Remington SPC

Participated in a T&E session with a 6.8SPC over the weekend. Due to its inclusion in an upcoming article(s), I can't name the rifle or ammo manufacturer.

The rifle upper was very well made with excellent fit & finish, as one would expect. No malfunctions whatsoever, & recoil only slightly more than a 5.56 stuffed with 80s.

However, the commercially loaded ammo left alot to be desired. It was some horribly fouling stuff, gritty in the locking lugs & barrel after shooting. Accuracy was disappointing too.

The good news is that the ammo is only test ammo - they haven't settled on anything specific until they get results in from the field. It's very possible that the optimum powder vs. gas tube 'node' is yet to be determined. Now that we have a supply of brass & some dies are on the way, some sweet handloads should be on the horizon. Time & testing will tell.

Re: 6.8 Remington SPC

A lot of the test ammo is powered by RAMSHOT powder - but the real Remington stuff uses a new proprietary propellent that delivers the goods. From the qualified reports I've read, the load shows terminal impact damage very close to the same as a 7.62, but much more compact and lightweight cartridges. BTW, there's been a load of arguments for years to adopt a .243 or similar cartridge for the M14 or similar platform and go with that. This new round beats the .243 and delivers performance very close to the .260 Remington.

For comparison, here's a 30 Rem - 6.8SPC - and a 5.56mm...



This new round also works at 10% less pressure than a 5.56mm NATO, and uses the same recoil spring & buffer from the M16/M4 platform. ALL THE RIFLES in current use need to be rebuilt - they're wore out. It's very cost effective and good for morale if the Military just installs NEW UPPERS with updated accessory rails & new magazines for the new round instead of just piddling around. ALL the tests that have been done in Afghanistan and IRAQ have given very positive results thus far! Just think of this new round from the M4 as a 9mm (weight) zippin' out there at 2700fps! GREAT for close range where many of the complaints have been noted. Long range, this is one deadly little bullet too!

GOOD LUCK! [img]images/icons/grin.gif[/img]

Re: 6.8 Remington SPC

What bullet is the government planning to stuff this new case with?

And when does anybody expect it to be put into the hands of soldiers for the real test?
