I've always said that there was room in the marketplace for 6.8SPC OR 6.5 Grendal , but not both .
6.5 Grendel just seems a little more popular. That could be because I own it and not 6.8SPC, but I certainly hear a lot more about 6.5 grendel. Though it seems like there are more 6.8spc loads out there. But 6.5 grendel ammo is easier to find.
A lot of places online sell 6.8spc.

The 6.8 spc didn't do anything that other cartridges weren't doing a lot better.
Yup.

Your right you don't see much in Ammo on dealers shelfs.

The hype about 6.8 spc and 6.5 grendel was that the military might adopt it as a replacement for 5.56. There have been rumors of a 6.8 cartridge for the Fn M249 prototype replacement for years, but so far theyve just been rumors. It might be 6.8 spc, or something else. Until they do, ammo will be expensive and few people will dive in.

Seems the DoD wants to bring back a flavor of it so maybe it will come back to life.
It wasn't a horrible round, but like many, it just wasn't worth the effort for the little gain.

Hope so then it will insure it's place in history as a US Service round.

Sig just announced last week they've developed a new 6.8mm cartridge(not 6.8spc) for their next gen saw submission.

Great links
Cool so it is an excellent round for shorter barreled rifles and probably AR Pistols. Enough hit to not miss a .300AAC? Wonder what ideal barrel length is for it. Like 300 length for pistol is around 9-10 inches.

6.8 spc is a good cartridge but didn't offer much on the battlefield that 5.56 isn't already capable of. Seems to be a fine hunting round for pigs and deer though.
The new 6.8mm cartridge that Sig introduced for NGSW is basically a necked down 7.62x51 cartridge constructed with novel casing materials to save a small amount of weight. The competition from Textron is a polymer cased round of some type with a 6.8mm bullet. Neither has much of anything in common with 6.8 SPC beyond using 6.8mm bullets. The Pentagon's performance requirements for NGSW means that rifle/ammo weight and recoil will be a problem until every soldier gets an exoskeleton standard issue. Personally I put this effort in the same bin as the M14 or SPIW. Except with supposed magnum level recoil. Which will cause requirements to change to the point that either the weapons/ammo are too heavy to carry or the ammo too weak for OVERMATCH. I don't think this sort of development program is a waste of money as it pushes innovation, and maybe the army will get a new SAW out of it. The battle rifle that goes with it is never going to make it past field trials since soldiers are not going to want to carry the extra weight, deal with the extra recoil, or put up with probable reliability issues induced by such a hot round.

Oddball caliber fan
Remington is what happened to the 6.8. They sent the wrong specs to SAAMI and it stuck the cartridge in a weird form of limbo. Some smaller companies came out with a spec 2, which was better than the standard and included a chamber with a longer leade and slower twist rate. That's where the cartridge really shined. Too little too late, and now it's a niche cartridge.

6.5 Grendel has more power, more range, better ballistics. 300BO is more efficient(especially from short barrels), more versatile, and can throw a larger slug, both stretch the platforms capabilities pretty far from the base 5.56 chambering. Of course 5.56 is more popular, and newer heavy/high BC bullets stretch out it's versatility enough to make the relatively small differences in 6.8 not really worth it IMO.
This!
Mostly agree with this. I don't think .300AAC was necessarily such a big impact, but I do think steel-cased 6.5G ammo made that caliber a much more appealing choice, since you could now use it in high-volume applications without breaking the bank. 6.8's only real use case now is a very marginal (and theoretical) increase in terminal/hunting performance over 6.5G at like 200yds and in, and maybe slightly better bullet selection. That's simply not a compelling argument given everything else 6.5G does much better.

Ok - I'll say it, I'm the grumpy old guy who gets annoyed at these "what happened to this or that caliber". Just like the 9mm vs .40 vs 45acp endless debate - it's a similar argument. 6.8 SPC didn't get the fame because as others said, there's a number of other perfectly fine rounds (6.5 grendel, .224 Valkyrie, .22 Nosler, etc). What hurt the 6.8 SPC adoption in my opinion, were the picky magazines. Had the military fielded, it would have likely been a different story. The differences, or lack there of, is one of the factors why the .300 BLK rose over most of the others (and size, energy and subsonic). As soon as the new 6.8 specs hit the market and some portion of the military jumps to and aftermarket adopts, there's a good chance that will be the new king in 3-5 years. These choices are like ice cream - pick what you pick to satisfy your needs and be done with it. Just understand what you do today could loose it's "coolness" tomorrow.

Hunting bullet wise, the 6.8 has it in spades. Unless bullet manufacturers got their 6.5 stuff together, all of the 6.5 bullets are designed to work at Swede, creed, 260, and x47 speeds. The 6.8 has bullets designed for performance of the specific cartridge instead of using 270 designed bullets. The round had really caught on in the hunting section. My 9 yo has one. He killed 2 deer with it last year and are trying out luck with bear next month.

The 6.5 bullets work fine for hunting in the 6.5 grendel. The SST expands just fine from a 16” barrel out to at least 400yds. 1600fps is the minimum required velocity for reliable expansion and from a 16” barrel Hornady SST has that out last 400yds.
I don’t plan on probably shooting at anything past 200yds, maybe 300 max with my 18” 6.5 grendel rifle. I am not worried about bullet performance.
