Just an interesting tid bit I picked up doing a search. What was said is that ammo makers are looking at making a 6.8 x 43 ammo that is hotter but do not want to make it so that it can be chambered in the 6.8 SPC I or II chambers. If such ammo was adopted by the military, it might obsolete the SPC II chambers and would have to re-chamber, a-la-chamber reamer to come to this new spec.
I saw this at the following link: http://www.co-ar15.com/forums/showthread.php?t=19114 Since I'm not a member of the Colorado AR-15 forums I couldn't ask questions. Do you think there is some validity to this story?
sounds to me like some guy proly jst now put two and two together....that stuff to me is considered old news since i have been pretty well informed of the latest and greatest 6.8 stuff thanks to this forum....but if what your saying is true they're gonna have to proly weld the primers in....lol. loads have and are already close to maxed out. i'm guessing that guy is talking about the older 1-10 twist barrels....that of which many have also been reamed out to spec II. from what i've read according to shot show reports remington is gonna offer a spec II with 1-11" twist. HTR was even sly enough to get us a snap shot of one of they're barrels. the 6.8x43 chamber would have the best chance at getting accepted by the military. it's proly the most combat reliable chamber currently avaliable; thanks to H. i'm sure ssa will still make commercial loads for all of us since so many older spec'd barrels are in existance. the military can load ammo however hot they want, but in my opinion there will most likely remain a civilian market for 6.8spc ammo. of course it proly won't be as popular in a few years so they may only sell combat loads...which is fine if you have a barrel with the current specs being offered.
Aww same old rumor monger who talks about a "New 6.8X43" with no data from what I see. Don't feed the Troll.
The VI POINT VIII Specification Eye Eye is Great!
What I never understood, is why they just didn't start out and re-design the cartridge brass to a different size to begin with! They used the 30 Remington and simpy worked with it and re-designed it a bit. I would think that making the brass the same OD as the 7.52 x 39 Soviet round, but longer at 43-45 mm would have given them larger case OD, meaning larger inside case capacity, neced down to .277 diameter with the correct throat and leade. I would not have made much differnce in case size, since you can get barrels and magazines for the 7.62 x 39 Soviet round to fit in the AR-15 schema as it is. Imgaine, instead of loading 28 gr of xxx behind a 115 bullet you could load 35 grains of xxx behind the 120 or 130 gr bullet and have it at the same or faster velocity as what you are getting with a 90 gr bullet out of the SPC II chambers?
I'll say this for the 10th time...
I'm actually jh308 on that board. I assumed BS, then was pretty sure of it after the response to my questions. Wasn't worth any more of my time after that.
Maybe his "source" had seen the ACR bbl, considering where Magpul is located, and just made an assumption?
ETA: I guess I should ask for an update since SHOT's over...

The ONLY "Common Sense Laws" that we need is the one that requires our Representative's to use it.
True, but what about the re-barreling of an AR-15 to 7.62 x 39? Change bolt, barrel and magazine.
