6.8 spc, is it worth it?

edited February 2008 in Ask the Experts
I have been tossing back and forth the idea of an AR in either 556 or 6.8. I don't want to open a can or worms by arguing that the 556 is or is not an effective round, but am leaning toward the 6.8. Anyway, the arguments against this round are
1. availability
2. $20 dollars a box (of 20)

However, everyone is familiar with the supply problems with 556 ammo and its price as well. It would seem that this situation would make the 6.8 a viable choice with regard to price and supply or am I off the mark? Thanks for the help. I have several months before I decide what I am getting and wanted to cover all bases.

    NOTPARS,

    As bad as supply and price for the .223 is it is still way better than 6.8. Even though it is slow, it has more hunting potential than does the 5.56mm(.223)

    Something I noted when shooting the 6.8 from an AR carbine(16" barrel) was that velocity wasn't very good. According to the owner he was zeroed at 6" high @ 100 and I had to hold at the top of the paper (22" tall) to hit just above the center {edit[:D]}@ 300. We estimated the velocity at 2100 fps. Those were factory rounds.

    The reason I include this is because for those of us who like the AR for the flat shooting trajectory, you will be disappointed.

    Honestly, I would look into one of the WSSM builds for performance or an AR-10 in .260 or .243. That is, if flat shooting hard hitting would be an issue for you.

    If you want to fart around with the 6.8 spc get a Contender 23" carbine barrel and frame. If you reload it is cheap enough to plink with.

    NOTPARS,

    I would skip the 6.8 SPC and move on to one of the newer cartridges that will work with the AR platform such as the 6.5 x 47 Lapua, 6.5 Creedmoor, 6mmXC Tubb, 6mm/250, 6.5/250, 260 Rem., .243 Win. and the .308 Win.

    These cartridges will outperform both the 5.56 and the 6.8 SPC. You will need to look at the ARs with the larger bolt to accommodate the larger rim diameter of the cartridges. Then learn to reload to maximize the performance of any of the cartridges.

    Is there any difference between a 6.8 lower AR assembly and a standard .223 lower? I didn't think so, but I haven't really looked into it. But, if they are the same then the answer is to have different uppers to swap over. I have for my .223 AR both a 16" Bushmaster and a 24" varmint uppers. One of the best aspects of the AR platform is its flexability.

    For Sandwarrior: Thanks, that is very important information. You see, I have an AR10. The problem with that is it is so heavy, and if for reasons beyond my control I had to carry 200 rounds, it gets to be a it much. I was looking for a lighter "battle rifle" and that included the ammo. But, I hear and read so much about how the 223 is not effective. Your input will definitely make me rethink this and I appreciate it.

    ern98: Great point. If I bought an AR from DPMS, Stag, and so forth in 6.8, I could swap a 223 upper on it fromt he same company. My real desire would be to buy one of each but that is out of my price range.

    For bgJohn" Makes a lot of sense to me. I really really need to learn to reload.

    For Nononsense: Excellent post and worth considering. Would any of the ones you listed be the 6.5 Grendel? What do you think of that round? The major reasons I considered the 556/6.8 is weight. If the feathers hit the fan and I had to carry one of these, the AR10 and 308 cammo gets heavy for this middle aged shooter. Thanks for the info. I have a lot to research.

    ADDED:

    NOTPARS,

    No, I didn't list the 6.5 Grendel. It's based on the 6PPC case which is derived from the original .220 Russian case. The case size is smaller than those that I listed. The rim is 0.445" in diameter.

    This is a list of article about a lot of the different cartridges:

    http://www.6mmbr.com/65grendel.html

    While I think it's a fine cartridge, it doesn't meet my needs, that's all. We all have different requirements and that's what makes reading all of these things interesting.

    Best.

    All of these require another upper receiver/barrel asm. That is talking about BUCK$! That is why I went the T/C Contender route.

    BG John,

    "I have been tossing back and forth the idea of an AR..."

    Because that's what he asked about.

    Stick with the 223. Effective? If one doesn't do it shoot again. Anything worth shooting is worth shooting twice![:0]

    He already has an AR-10 (308). If that isn't enough bang he will need a 50 caliber.

    For bgJohn: Yep, already have the AR10 and the problem is too much weight and bang for the buck for me. I have a bad back/neck combo and what I carry can cause a problem so I was looking for an "effective" combat round closer to the 223 round in weight and size. Do you believe the 223 would be an "effective" self-defense type round in a suburban semi-rural area (effective meaning up to maybe 150 yards but no more)? I am hesitant to ask this question because I know the arguments that can break out over the 223 but, on the other hand, I like to read what people in the know have to say and that would be you. Thanks for the help.
