Those two words are why I haven't (yet) put money into 6.8SPC. No matter how good the cartridge, it is no good if you can't keep the gun running over time.

Justice Robert Jackson, WV St. Board of Education v. Barnette, 319 U.S. 624 (1943)

Yes, from more than a couple reliable sources, but anytime I bring them up the "experts" quickly tell me I'm full of shit, and the issues were faulty parts and not the cartridges fault. But - those issues were with the cartridges loaded to the specs of what they were supposed to be, not the lower pressure round they ended up as.
The ONLY reason to buy a 6.8 is bacause you want one. If you sleep better at night because you convinced yourself you have a more deadly carbine, good for you, enjoy your hobby.

The only bolt breakage data I had was from the earlier spec'd ammo
Anyone ask Zak what life he is getting? However I hardly view replacing a bolt at a rate that is about twice the 5.56mm to be a deal breaker.

Doesn't that sorta' depends on if we are talkin' DPMS- or Colt-made bolts?
Would it not depend also on the price and availability of said bolt?
At what round count do you replace a 5.56mm bolt?
This reminds me of the "Perfection" of 9mm Glocksbeing lost when the design was scaled up into larger calibers.
An Active Duty SF Sergeant used to publish a quarterly entitled, The Resister. He once included a political cartoon of a carbine in a case with a glass front with a hammer attached to the frame. Under it were the words "BREAK GLASS IN CASE OF TYRANNY". Oh, it is a hobby; nevertheless, it is much, much more.

I’m sure a lot of folks lose sleep over just that. Not me. When it comes to that, the willingness of the individual will be what matters. The caliber of the weapon is insignificant, be it a .22 revolver or a U-Haul full of fertilizer and diesel fuel.
You need to do/buy/train as you see fit. When the times comes you'll be responsible for your decisions.

And for those of you who already have a 6.8, what kind of accuracy did you get, and at what ranges??

With commercial ammo ( Remington, Hornady, SSA Xtreme ) you can expect to get 1.25 MOA @ 100 with an good AR. With a bolt gun it will be better.
With handlaods, and SSA matchkings You can probably get pretty close to 1 MOA @ 100. At least thats what its been for me so far.
My 6.8 has a 16.1 noveske, and a 6x scope, and I know the trigger puller isnt the best. I would assume that if you had a 20 or 24" brl it might be more accurate.

Do grendel guns have the around the same ammount of bolt failures also?

Well.. that means we'd be getting 1500-4000 rounds out of a 6.8 bolt, 1500 in a hard-run gun. I'm all for PMCS, but a gun that may have a bolt failure after 1500 rounds is unsat, in my book. Especially when I can get 80% of the 6.8's performance out of MK262 in a properly set up gun.
piss poor cost:benefit ration for me but Ymmv.
