    i am looking to buy an assailt rifle (before hilary bans them) i want something i can hunt with out to 400 yards, and i want to use it as a plinker to so it can't be a mule when it comes to kick. i looked at DPMS and they have a couple rifles in .260 remington which seems pretty interesting to me. good velocity and energy out to 1000 yards. how would it suffice in a short barreled, semi auto platform though? should i look somewhere else like .308? or would this do for my needs? thx

    It's not an "assult rifle", it is a "Sport Utility Rifle"... and yes buy as many as you can afford!

    For the odd ball calibers I'd take a bump over to AR15..com

    I'm considering a 6.8SPC upper, but have 2 projects before that... just as you, I'm looking at the 6.8spc as it is a .277 and legal for deer hunting.

    My current project is a 5.56mm Special Purpose Rifle Upper, done cheap, but it has been interesting, the next project is a Fulton Armory .308 AR... (I'm getting to the point). I already have the reciever and it interchanges with DPMS .308 parts, being about ready to build a .308 I've learned the follow.

    From what I'm told by guys that shoot, and from what I've found on the net, .308 out of a 16" barrel looses alot of it's ballistics performance, for a 'deer rifle' or longer range rifle a 20" barrel is advised... that is unless you plan to clear houses with it. A few guys have argued that a 18" barrel only looses a bit less than a 20" but everyone seems to say that .308 out of a 16" barrel and you might as well just stick with a normal 5.56mm AR15.

    What I can tell you is DPMS has a decent reputation, not the best, but they do have a good customer service reputation that makes up for it.

    AR's are a sickness, almost as bad as 1911's, but 1911's don't take up as much space.

    Please know that AR's aren't LEGOs... but since they can be 'pieced together' they are really economical and then you get to the point were you start building them from scratch just for giggles.

    They make a 24" barrel model of the AR10 in .260, that would be the cat's a** for both medium range hunting and target shooting. You should be able to stay supersonic with the right load out to 1000 and there are some excellent 6.5mm bullets available for both hunting and target shooting. I don't think any of the choices will work at 1000 without a 24" barrel minimum, nd 26-28 would be better.

    In the AR15 to get similar performance the 6.5 Grendel seems to be the ticket, the ballistics charts I have seen are a good bit better than the 6.8 SPC at 400 yards and longer.

    I'm looking at getting something else in the next couple of months and am still torn between the .260 on an AR10 or just get a long barrelled 6.5 Grendel for my current AR15 lowers.

    I have read that there isnt much of a loss from a carbine ar10 in 308.

    click- the 308 does have a measurable performance difference between long barrels (26") and shorter barrels (22"). if that loss is worth getting worked up about is an individual's decision.

    i do not have any experience w/ the 260, so can't even make a good guess...

    KC&97TA, thx for the correction there. now i have a decision to make wether to stick with the 7 mag i own, or get a .260 for long range. if i could find a way to keep barrel heat down on the 7mm it would be the perfect gun! ( in my opinion) anyway, getting back to the topic, what would be some good choices to fire out of a so called "sport utility rifle" remember i will only be shooting this gun at about 400 yards max with iron sights.

    The 6.8SPC is a little light in the energy department for 400 yard shots at mule deer, but inside of that it's likely all you'll need. I prefer it over the 'full size' chamberings both for the recoil difference as well as the fact that I can build a quality AR-15 in 6.8SPC to be several POUNDS lighter than a comparable AR10 platform. For a field gun, that weight difference is pretty important. If you're doing a lot of shooting at the range or from a stand, then the extra energy of the 260 is probably more compelling.

    I hunt by stalking. Given that, my AR10s mostly sit in the safe while I use the snot outta my 6.8SPCs.

    the 260 in an ar is totally unecessary, and the ammo is rediculous cost, unless you are reloading. other wise go with a 223, or 308, or even a 243, and if you must have somehting exotic, get a 6.5 grendel. At least the ammo isn't too much , and it is mfgr by wolf.

    okay, i know the grendel is a good round. I just don't like the thing, so i realy prefer not to have anything in that caliber. i have started to reaload lately so ammo isn't that big of an issue with me, i just want something with knock down power that will hit where i want when i want it

    I have both and I can tell you the AR10 is h-e-v, heavy! Stick with the AR15 platform. I happen to LOVE the .260 for deer sized game but have to second the fact that it is stupid expensive and occasionally hard to find. If you don't handload the .243 would be a much, much better factory cartridge.

    Having said that I don't have a 6.8SPC, so check the ballistics and compare for yourself.

    Zak, that was a well written, and informative article.

    Zak, I've always wondered, why not the .270? Some bullets have even higher BC's than 260 bullets and by most/all accounts the ballistics (wind drift, drop, energy) better the .260, while still maintaning most of the advantages of NOT shooting a 30 caliber magnum.

    Any ideas why the .270 Winchester has never really caught on?

    Find all the bullets in 0.277" that have a BC of at least 0.60. Then repeat the process for 6.5mm and 7mm. I think that will be your answer.

    And the lack of match grade factory ammo...

    Who makes a high BC 270 bullet? Compared to a 6.5?

    Ain't it a shame? The biggest SMK I could find for the .270 is 135 Gr.

    We need a .277 155 Gr VLD (Berger...Sierra? Lapua: Make brass!) We could get Jack O'Connor reincarnated with just new bullets and Lapua brass in .270 Win ;)

    On the same case, we already have 6.5-06 and .280 Remington, so I don't see it happening for the .270WIN.

    Two fine cartridges, and in a potential sweet spot in between...no good match bullets. From an engineering perspective, there is no good reason why Sierra couldn't make a .277/6.8mm SMK with a BC like a .264/6.5mm 142 SMK or a 175 GR .284/7mm SMK.

    The .270 Win was just typecast as a hunting cartridge, with little demand.

    But say a 155ish SMK or VLD in .277 would have less recoil than the 7mm, and more 'newtonian mojo' than the 142 Gr 6.5 SMK...

    If only we had Jack O'Conner to write Sierra, Berger, and Lapua!

    I just went through the 260 vs 243 vs 7mm-08 and decided on the 243 for varmit and deer. My deciding factors were cost, recoil and performance.

    i did some research and the 6.8 spc has disapointing ballistics compared to the .308 and .260 even out of a 20" barrel.
    i researched ballistics(averages)at muzzle and 400 yards w/ 20" barrels muzzle 400 yards
    .260-2700fps/2200lbs. 2000fps/1200lbs.
    .308-2550fps/2500lbs. 1800fps/1300lbs.
    6.8-2500fps/1650lbs. 1500fps/650lbs.
    so the .260 and the .308 both have their pros and cons, but it seems the 260 is the one i will be going with.

    Well, the 6.8 SPC and 6.5 Grendel fit in an AR-15, which is a much smaller and lighter platform than the AR-10, which you need for 260 and 308.
