I'm keeping my caliber's that I have to purchase ammo for to a minimum. For HD/SD the 5.56 round has made a lot of bad guys dead. 6.8 is cool, but until I can buy it at Walmart (aka anywhere) I'm not gonna bother. Right now my primary concern is getting enough that I feel comfortable (yea, like that'll ever happen!), not adding more ammo choices to the mix.
YMMV |

Given the election of Our Savior, you need to consider ammunition availability. .223/5.56 will be laying on the ground, 6.8 not so much.

Meh, I'll be the contrarian and say that I'm dumping all my 5.56 stuff in favor of 6.8 as a utility round, and 5.45 as a plinking round.

If you want a all around useful rifle that is fun,accurate and somewhat reasonable cost wise to shoot (compared to other rifle rounds) the 5.56 is really got to be your first purchase.
If your first priority is hunting or you foresee zombies coming over the hill 500 or 600 yards away and this rifle is the only one you will have I guess the 6.8 has got to be a consideration. For most situations even a second or third 5.56 (in some other configuration) will be far more useful than the 6.8. I own some medium bolt guns so even though I own like 6 Ar's I seem to set a higher priority on more 5.56 stuff than I do on the 6.8 |

Well......I definitely got a lot of feedback and it seems that the 5.56 will, indeed, be more plentiful and cheaper than the 6.8 right now. (I already have the 7.62 round platform covered. Thanks.) I just want to ensure that my decision won't haunt me down the road someday. I like the 5.56. Having spoken to some " operators " , accuracy seems to be in order with this round or any round. I have never seen nor shot the 6.8 but have heard good things about it.
( Damn that president - elect for making me spend more money when I don't have it ! ) I appreciate all of you for your genuine comments and good luck to all in obtaining that which will be no more. |

The choice is really between 5.56 NATO and 7.62 NATO (.308). An AR-10 would look good in your safe.
PS: I didn't see your last post about having 308 covered. |

Much debate has gone on about which one pokes a nastier hole. I propose that NO 1-man portable, shoulder-fired, non explosive projectile (I am sure someone will cite a 101mm recoil-less or somethign stupid and argue with me...) will incapacitate someone IMMEDIATELY without hitting a CNS structure.
A 5.56 to the cerebrospinal region is just as destructive as a 6.8 round. The ONLY argument that can be made for the 6.8 is that the larger round will fragment more and have a better chance of hitting the spinal column from a frontal shot. (or that it will go through glass more reliably, but they make TBBC for that). Basically I am trying to say that you won't stop someone IMMEDIATELY due to physiological incapacitation unless you hit the CNS and then both rounds will be equal. Ergo, for me, it comes down to ammunition availability. A hole in the CNS is a hole in the CNS. Anything else requires a 20% total vol. blood-loss to be effetive. Even cutting a limb off would not cause this quick enough to prevent you being shot in return or knifed if the assailant is reasonably near you. Shot placement shot placement shot placement. How is this achieved? Practice. What does this require? Ammo. Again, 5.56. Just my .02 |

I think that 6.8mm SPC is cool too, but it costs 2x as much to shoot compared to 5.56mm ammo for us commoners. I would vote for the 5.56mm stuff for civi use, but 6.8mm ammo for the military, since they can buy whatever they want and this gives our GIs a better edge on the battlefield.

No 6.8 Pmags. I am perfectly happy with my 5.56 LWRC M6. Cheaper ammo. Better ammo availablity. Mags hold more. I can use Pmags. Quieter suppressed. Less recoil.
I will get a 7.62 LWRC SABR eventually and THEN might consider a 6.8 but not untill I have 5.56 and 7.62x51 covered. |

Which is why the ole fashioned Remington pump action is my go-to weapon if I hear bump in the night. With 9 pellets, 9x the chance of hitting the spine per shot. |

6.8 is great if you can feed it. If I could afford it i would trade most of my 5.56 uppers for 6.8. But... Ammo is harder to find and pay for. I don't regret getting the 5.56. It's always a hard decision every time I get a new upper though.

I was within a single expendable pay check of switching over to the 6.8
but did some more homework before placing the orders. I think the 6.8 loses much of its luster when you start using SP or OTM bullets in the .223/5.56mm. Yes, I know that SP /OTM 6.8's will make a slightly larger wound but IMO it's a diminishing return when you compare the cost and availability of same to .223 expanding loads. Handloaded .223's are a lot cheaper than home brewed 6.8's. There are also a much greater number of choices in brass and bullets. Finally, I'm a proponent of Magpul PMags. They are presently available only in 5.56 NATO. IMO if you're on any kind of a shooting budget, .223/5.56 is the way to go. |

Not only is 6.8 significanly larger, it's a more optimal wound profile (i.e. shorter neck) and more consistant results (far fewer issues with 'fleet yaw') . 6.8 will also still make FBI/IWBA minimum wounds after passing through barriers (including a chest pouch loaded with full AK magazines) something no 5.56 FMJ or OTM round can do. |

I would say get the 5.56mm only beacuse the ammo is cheaper and plentiful. I think the 6.8 is a great round and would love to have one but I don't see the ammo in many places and when I do see it it's usually pricey. I would rather have something I could afford to shoot than something that sits in the safe all of the time.

A few years from now, 5.56 will remain the much easier to obtain ammunition.
However, if you want to reload, both are similar in price for nice components. |

Good lord that stuff is expensive. Even Ammo to go doesn't have deals on 6.8

I agree with forest on the 6.8. I would get an LMT CQB MRP (I have two) and you can use both 5.56MM and 6.8SPC. And yes I run SSA 115gr loadings with no over pressure signs. |
