View Full Version : Long Range AR- 223 wssm vs. 6.5 grendel
August 30, 2012, 06:40 PM
Looking to build a long range gun in the ar-15 platform. Would the 223 wssm or 6.5 grendel be better as far as long range?? Which one is more accurate at 1000 yards. how far can they stay supersonic?? how far can you shoot accurately with them??

Hey,you wouldnt happen to be in the military would you? ...Maybe just got off a deployment??? If so you might know me:)
Depends on what your doing with said build would d3pend on what of those 2 calibers Ide choose...ALSO, "how accurate" are they depends more on shooter assuming a "good" weapon has been built. Both of those calibers, given the proper platform, barrel, also ammunition (and other factors...i.e. rate-of-twist, grain weight, to name a few) should yield some amazing results at extended ranges.

I vote Grendel. I have never even seen a WSSM AR and all the 6.5 Grendel ARs that I have ever shot have been SWEET.

the 6.5 is has a great BC for long range. go for it!

Thanks for the replies and ; "common sense" no i am not in the military I am just an experienced shooter looking to get into long range shooting. I think im probably going to go with the grendel after the replies and some extra research ive been doing:).

I'd personally skip the .223 WSSM and jump to the .243 WSSM if you are looking for long range. Just my .02$

How well does the 243wssm hold up at 1000 plus yards?

http://www.snipercountry.com/Articles/243_WSSM.asp this is a decent write-up on the .243 WSSM, if you go far enough there is a ballistic chart you can see as well.

I would skip both and just get a .243, .243 WSSM is a very marginal gain on it for the expense you give up in ammunition and bore wear you'll give up with the cartridge being so over-bore.

the .243 only fits into an AR-10 size action I think the OP is looking for a 15 sized action, though if I'm wrong, I would also go with the .243. Or, if I was going to step up to the AR-10 size platform, the Creedmoor or the .260 are VERY nice.

You're right, the .243 won't work in an AR-15 platform, the OAL is too high. I just feel like getting an AR in .243 WSSM would be an undesirable compromise, though. You'll save money in the short run because all you'd need is an upper (assuming you already have an AR-15), but lose it in the long if buying ammunition. If handloading, it's probably the best option financially.

.243 WSSM is a bad-ass in the AR-15 platform...I'm sure the barrels aren't easy to find, nor cheap...but OOOHHHH the ballistics. I haven't run them against the 6.5 Grendel, but I'll bet they're impressive.
Shooting heavier bullets should keep the barrel life acceptable. I've read that mods are required for the magazines, don't know much about it.
But I can't see an advantage in any usage for the .223 wssm over the 6.5 Grendel for long range. The heavier, higher BC pills will rule. You could push those smaller .223's fast, but you're going to buy a lot of barrels in the process.

6.5 Grendel will begin crushing .223 WSSM once you get past the point blank range of either round.

Note that the US Army Advanced Marksmanship Unit finally gave up on the 5.56 NATO round for 1000 yard service rifle matches. They were tired of having their butts kicked by folks shooting 7.62 NATO ammo from M1's and M1A's that shot much better scores. So they got the NRA to classify the AR10 as a service rifle and that's what the USAAMU used at this year's Nationals to set a new team record.
Any one of numerous 26 caliber cartrigdes shooting 140's or so fast enough to remain supersonic at 1000 will out perform the 22 caliber rounds in AR15 platforms. If the wind's not blowing, a 6XC might do well in AR15 size platforms.

A 243 WSSM launching a 115gr DTAC bullet is a solid long range option. Not much can beat it from an AR-15 length platform.
