6.8 SPC? 30Rem/270

[buck1]

I never heard of this before. What i have learned , its a mil Special Purpose Cartridge Hence SPC.
A 30 remington case shortened and necked to .277 dia fireing a 115 gr bullet @2600-2800 Fps. The pressures are low enugh to work in a contender.
It looks as if it may be very cast friendly?
Any comments on this cartridge? Thanks...........Buck

Looks like it has flopped before it ever got off the ground, Buck.

Buck, you wouldn't be real far off that case if you took a 30-30 AI and necked it to 7mm. Think of a 7-30 Waters Improved. I'm sure there is enough difference to argue over, but I doubt there is enough to matter. It ought to make a real nice cast shooter. Methinks that the 6.8 is being loaded by a couple companies now, and TC is offering it as a standard chambering. Look on midways ammo pages. It is a Leftoverdj has said though, all the appearances of stillbirth.

Buck1,
IIRC, this was developed as the largest base case size that they could fit into an M-16 and magazines and get to feed. The reports that I've skimed in the gunrags said that it was MUCH more effective than the .223 on large 2-legged varmints especially at longer ranges.
I believe that Rem. is chambering a bolt gun for it now and seem to recall reading that Ronnie Barrett has exclusive rights to make uppers for the M-16/AR-15.
The performance seems to be about the same as the ancient .270 Titus Savage so it hasn't really caught on with those who believe that whitetails require a .339 Eargesplittenloudenboomer.:coffee::bigsmyl2:

Yeah, the most of the Savage line of cases contain about 40 grains of 760. The 30Remington, is a 30-30 without the rim, and its capacity is around 35 grains of 748. This would mean the military would have plenty of powder already made up to load the 270 Rremington. H380-H414 military equivalent. ... felix

[Leftoverdj]

There have been rumors over the last year that CZ will offer their 527 in 6.8 SPC. I'll believe it when I see it, but that would be a very neat lightweight package with performance matching the .250 Savage. I'd love to see it, but I don't expect it to happen.

Gang-this was/is an idea that is getting kicked around the military; particularily the SpecOps community. Seems that they've finally figured out that a 5.56 doesn't really put people down fast enough, especially when you're clearing rooms; BTW most of those SpecOps boys are carrying .45 ACP's instead of nines for the same reason. DoD may finally make a switch, but almost definitely not before I retire, (3years & 69 days, but who's counting). Unless DoD switches over I think the cartridge will be a dead horse; though I have seen ammunition for it up here in Eagle River of all places.

Ballistics sound similar to the 6mm Lee Navy. What goes around, comes around.

Try to look up the 276 Pederson and you'll see that the Brits were talking about this size round since the 30's and we bullwhipped them into accepting the 7.62 NATO round.

The more things change the more they stay the same!!

What got me intrested is the small case( MIL SURPLUS in the future if it worked out) Low pressure , small powder charge( again mil surplus some day).
It seemed to add up to a lot of low price varmit hunting.
For a jacketed bullet its rather like warm vanilla ice cream , But as a cast gun it looked like it may have had something to offer and in cheap factory brass. ........Buck

Good thinking. I've been tempted by it. If I had an AR15, I definitely would buy an upper for it. As a military/police round, it has advantages over the .223 in certain applications. And they have interest in wounding/killing people at 500-600 yards. Its bullet weight limits it to small deer at most and sub 200 yards at that. And what decided me not to get a bolt gun or Contender barrel for it, was the simple fact that we already have guns that will do that very same job; They call them .30-30s. A .30-30 with the right bullet of 125 to 150 grains will outperform the 6.8 at 200 yards. Just not worth the trouble at all for us silivillians. I hope someone markets an upper for the parent cartridge, .30 Remington. That ought to work and eliminate the problems they have with 7.62X39 uppers.

I've got that baby necked up to .321 - a Rem M81 semiauto - the cartridge is called the .32 Remington rimless. It is a great cast bullet cartridge, handling up to a 200 gr. cast bullet with all the medium speed powder (3031, AA2460) you can stuff in the case. I suppose you could call it an 8mm SPC.
The .270 with cast bullets is interesting, weights running around 105 to 150 gr., and there is no reason you couldn't get the same CAST bullet ballistics with the 6.8mm as you can with the .270 Win. OAL might be a problem with the long 150 grainers, causing them to be deep-seated.

FWIW, got the new ( June) Handloader yesterday which has a small writeup on this little beastie. It seems that Remington was having some problems with performance at very low and very high temperatures, problems with their dies for forming the brass, and problems with accuracy. They claim that they have all of these solved now and plan on releasing the cartridge in 4 more rifle models this year. Maybe they'll cut in loose in the Model 7 or a light version of their baby 98 Mouser ( model 799??) that I saw a very small blurb on.:holysheep

News to me. The .250 Savage with near identical ballistics has always been considered a 300 yard gun on deer of any size.

You ain't gonna squeeze a .30-30 into a Mini Mauser nor a CZ 527, neither. To make a .30-30 match a 6.8 or even a 7.62x39 at 200 yards, you are going to have to go to a pointed bullet.
