Another Grendel tip: the Hornady 123g Amax and the SST are ballistically identical, pretty much shoot to same POI.
There are Berger, Barnes, etc loadings, but the Hornady 123g profile was optimized for the Grendel and just works great in both Match and hunting loadings. The Amax loading is extremely accurate in most guns, had one heavy barrel Grendel that the most accurate I've ever owned with factory Hornady.
To be clear, you won't get creedmore velocities. Go AR10 if you want that. But for a light recoiling gamestopper in the AR15 form factor, hard to beat. Especially if you like to shoot past 100yds.
As most of the AMAX line has been phased out, I'm interested to see if the 123gr ELD will yield similar results as did the AMAX. As there are both 120 and 123 gr 6.5mm ELD's, I'm assuming the latter is still made with the Grendel in mind, but in haven't done any testing yet.
I also love Grendel. Great stuff.
There's a small ammunition maker near the range where I shoot. A couple weeks ago, he was testing 175 gn .308 ELD vs. AMAX, since as you mentioned AMAX is being phased out. He found that while the ELD was just as consistent as the AMAX, there was close to an MOA shift right on POI (almost no wind that day and shooting 100-300 yds). We were puzzled by this.
Last weekend, I brought out my 168 gn .308 ELD & AMAX loads, and had similar results. I don't know that will carry over to 6.5 projectiles, and I've only loaded ELD for Grendel, but it goes to show why it's recommended to zero based on ammo.

Ditto on the Grendel or other AR15 compatible 6mm or 6.5. That said, I have no problems w/ my -39mm AR. I'd bet good handloading could turn it into a 300-yd antelope rifle. Accuracy in that caliber is amazing!
You mentioned mag capacity, but many states limit the amount to no more than 5 total, so you may need to block even a 5-rnd mag so that w/ round in chamber there's only 5 max.
Given that 10-shots are a group and 5-shots may be a favorable trend ... know that just one good 3-shot group can make you an instant internet superstar!
Naw man. You can get a Howa bull barreled mini action and an lss chassis. That would be one very nice bolt gun. http://www.brownells.com/rifle-parts...prod95995.aspx

I did the same research earlier this year. The 6.8spc and 6.5g will both be the functionally the same at 300yds.
6.8 bolts are stronger (more material) with more factory ammo choices. Designed for shorter barrels.
6.5g is the sexy caliber at the moment. Better than 6.8 for long range target past 500yds. Considered more prone to jam when feeding (conditions vary). Designed for longer barrels.
I have both. But for deer hunting, a 16" 6.8spc (ARP) barrel in the woods gives a true recce AR15 type system that uses the full potential of the round. If you like hunting with long barrels, an 18-20" Grendel is considered the best compromise though full potential is from a 24" barrel (as I recall).
And if you want a 6.5 in a 6.8 spc case, that wildcat option is out there.
This has been hashed out in many threads and often devolves into a heated debate for some odd reason. Here in Montana, several of us went through this debate back in 2011-12 and then later in 2015. Several of us, myself included built 6.8 SPC II rifles. In 2 seasons we have harvested: 3 Antelope (Ranges 200-300), 1 Cow Elk (350 YDS), 1 Large Whitetail buck (<100 YDS), 1 Large Muley Buck (355 YDS) all with the 6.8 SPC.
Between case profile as it relates to feeding, bullet selection, barrel lengths with performance, logistical support of ammunition and the 15+ and growing manufactures who produce OEM 6.8s, among other factors we chose the 6.8. Ultimately I see us loading up some 130 grain custom loads for the 6.8 in the future.
The 6.8 is awesome and I am very happy with it.
You can't make a honest argument against the 5.56 with the bullets available these days. "Energy" is not measure of wounding ability, and bonded or solid copper have plenty of penetration for deer.
300 BLK, 7.62x39, and 30-30 I would consider functionally identical for hunting. I'd pick 300 BLK for feeding in an AR over 7.62x39.
If you want a bit more range and bullet weight there is nothing wrong with that. The 6.8 and 6.5 don't have much difference at hunting ranges. Pick what you like and avoid the crazy arguments that people get into over them.
One thing I have to say about the 6.5 is I don't think it has any range advantage for hunting. Bullet performance should limit the range for ethical hunting before any real ballistic difference.
I've seen both more hunting bullets and loads for the 6.8 on the shelf, in my AO at least. Your AO may be different or if you buy online then it's not a concern.
