Speaking of ammo availability, here's something posted today in another forum:
I was at the local Cabela's today. They follow the basic retailer rule of carrying a "just-in-time" inventory. They base their stocking/shelf quantities on the rate at which something sells. If it sells they carry it. If it doesn't sell they get rid of it and don't carry it anymore. If it sells fast they carry more. If it sells slow they carry less.
Cabela's was carrying six different 6.8 SPC loadings. That's up from a few years ago and it wasn't too far back they didn't carry any 6.8. Cabela's was also carrying over a dozen 6.5 Creedmoor loadings. But they carried zero, zilch, nada, zip in 6.5 Grendel. There was no shelf space dedicated to Grendel cartridges so it wasn't just a matter of being out of stock. They no longer carry it. It seems to me like the 6.5 Creedmoor is supplanting the Grendel cartridge. I can understand why. It also suggests an increasing trend in people choosing 6.8 SPC when looking for a medium bore cartridge for the AR15. View Quote -Stooxie |

I jumped on the 6.8 bandwagon early, when it and the 6.5 grendel were still in competition, and it seems the Grendel has won out in recent years. I own a 6.8 and it is a great round, but were I to do it again today I'd go with the Grendel. View Quote That said, mine is very light and handy with a 14.5" barrel when a can isn't attached. I carry it regularly on the lease, because it will take down anything out there and does reasonably well at 500yd |

6.5G has only one advantage over 6.8SPC: those long skinny bullets that fly straighter.
Inside 200 yards: 6.8SPC wins 200-350: roughly equal 350 +: 6.5G wins Past roughly 400-450 yards, neither one has the retained energy to make ethical kills. That mean that the 6.5G's advantage is almost all for paper punching at distance. 6.5G bolts are weaker, due to the larger head diameter. That doesn't mean there are lots of broken bolts. |

If you already have an AR chambered in 5.56, do yourself a favor and buy some quality ammo like gold dots or some black hills TMK. They preform very well and will meet you needs. If not, build whatever interests you the most and shoot it because bullets and shot placement matter a lot more than headstamps.

OP, understand that there is a pocket of extreme fanaticism about 6.5 Grendel here. The absolute mathematical fact is that 6.8 SPC is a better deer load under 400 yards. The Grendel folks only talk about one thing: superior ballistic coefficients past 500 yards and shooting long distance. Take that away and there's zero argument left. This has been debated 1000 times at arfcom and the folks with 33,000 posts in just a few years always win out with ready copy-and-paste diatribes. Do your OWN research, and I promise you, you'll see a different story. To get back to your actual question, yes, it is absolutely worth it. I've killed deer with 300BLK, 7mm-08, 6.8, 270win, 308, etc, and 6.8 SPC is terrific. I liked 300BLK but just didn't feel (rightly or wrongly) that it anchored the deer well enough (which is 90% shot placement anyway), didn't love it's slow trajectories and didn't love that there is really only one choice of hunting bullet. 6.8 SPC has given me everything *I * was looking for: -Small frame AR compatible -"normal" case profile (i.e. not a short/fat case) -Super easy to shoot, very little recoil -Larger case capacity providing much higher velocities -Oodles of available, cheap, accurate and deadly factory hunting loads -Terrific results on deer-- DRTs from 90gr pills to 120gr pills. (Shot placement is always the #1 factor) -Excellent velocities out of short barrels-- 2750 fps from 90gr Fusion in a 12.5" barrel -High velocities from just 18": 2970fps for the same ammo -Easy to buy parts, cheap sub-moa nitride barrels I don't care about ringing steel at 800 yards or taking shots at live animals past 300 yards.

You have given me lots to look into, & investigate, & tons of YouTube videos to watch. I didn't know the world of 6+ cartridges was so loaded with fanatics. |

I built a 6.8 for my first gun. Eventually converted it to 5.56 so I could actually shoot it. Ammos too pricey and I wasn't doing anything with it that would justify the cost. Fast forward to today 10 years later and I'm doing a 6.5 grendel SBR. 6.8 wasn't even considered. They're pretty similar ballistically until you get past 500 where the grendel starts to get ahead but its not night and day like the 308 and 6.5 creedmoor.
I would just get the grendel if you already have a 5.56. |

I'm working on my third 6.8 build. Currently I've got a 16" and a 12.5". My next will be shorter, probably 7.5 inches. I've got a lot of the Gold Dot 6.8 that I picked up at a reasonable price. It will do about 2400fps from an 8 inch barrel. So this next build will be all out PDW sized. Probably a Maxim PDW stock, 7" 2A rail, 7.5" barrel, LWRC 6.8 bolt, ADM ambi lower and a Dead Air Wolf in K configuration. So far I've got the bolt and rail

My 12.5” 6.8 lauches my handloaded 120gr SST to 2450 at basically sea level and 2480 at 6500ft ish where I hunt. A 12.5” Grendel can’t do that. It is devastating on deer.
You should limit your effective range, not on an arbitrary number like 500, but rather the combination of minimum expansion velocity and energy. With that said, I believe that the 6.5G is a better factory round. Factory 6.8 is neutered b/c of ridiculous SAAMI foul up from Remington. As a hand loader, I can get the most out of the cartridge. Here is the truth, for hunting either will work fine. |

How do the full size mags compare between the two calibers? It looks like the Grendel mags have more of a curve. Any reliability issues?
I would assume the smaller mags, like 10 rds. would be about the same. |

It works great on deer. My son has claimed my 6.8 so I have been considering what to build next. Was thinking about 6.5 but I'm interested in what the Army is doing.

I went 6.8spc a little less than roughly 7 years ago. After doing a TON of research between 300BO and 6.5G I chose 6.8spc for the simple fact that I would be hunting at 350 yards and less. I'm happy and given the chance to go back I'd do it again. Nothing has changed since then. It still is the best option for that in my opinion.
With that said I have considered doing a 6.5g for a long range paper target rifle. With all these lowers from PSA I might just do that. Who knows. |

I've been killing a deer per year for the last 10 years with a 6.8 SPC either a frankenbuild AR or my Ruger Compact bolt action. Also numerous coyotes and occasional vermin.
It kills everything DRT and I have been very satisfied with the round. 90 grain TNT's are my standard road hunting load and for deer a 120 grain Pro Hunter load is very effective. A Barnes TTSX 95 grain is my favorite deer bullet. So far it's been one bullet per deer and I haven't had to shoot one twice. I see no need to throw my 6.8's away and bet you would be well served by the caliber. |

I'm a 6.8 user, I knew of the 6.5 at the time but still chose the 6.8 and stocked up on SSA ammo when they were still pumping out their tactical 110gr. soft points. I prefer the case dimension/profile over the 6.5g and I'm not a >300yard shooter anyway, not even with my .30-06. People talk like the 6.8spc is going extinct, it is not, I can find ammo all day long on-line and usually at the local Wal-Mart too. It is not produced by wolf, but it's not quality match ammo anyway, plinking ammo. If Wolf produced ammo in 6.8spc I'd probably pick some up just to have as well. I like to remind people of the development of the 6.8 where various calibers were tested and although the 6.5 exhibited the best accuracy, the 7mm proved to be the most destructive. The 6.8 was found to have the best compromise in accuracy and destructiveness. I don't fault people for choosing whatever caliber they choose, but I wince whenever people bash others' choices in caliber. There is always a better caliber out there for whatever metric you might be gauging one by. Since the 6.8 and 6.5g were introduced there has been this unabated hostility by the 6.5g crowd towards the 6.8spc users, that has helped fortify my allegiance to the 6.8spc as well. View Quote |

I've been in the 6.8 game for about 3 years now. I've shot a lot of deer with a lot of different stuff, but the 6.8 just plain works. A few coyotes and a nice hog too. It just puts them down. I wouldn't take a shot over 300 yards with it, but then again, I probably won't ever shoot at a deer over 300 yards with anything. 14.5" barrel and a Trijicon 3-9 is about as handy as it gets in the deer woods in my eyes.

Most of what has been reported about the 6.8 history is a fabrication. The terminal ballistics tests done by the small handful of people intentionally refused to look at decades of Army research dating back to the pig studies and the .276 Pedersen, then rigged the tests with different projectile construction in favor of .277 diameter for some reason. http://www.itstactical.com/wp-content/uploads/2009/07/pic9.jpg The FBI ballistics lab looked at those attempts to rig the tests and told the handful of 6.8 promoters to never come back again. Then they hoodwinked a USMC General into thinking it was the next best thing for the Corps, and tried to rig more tests against the Grendel by ordering pallets of the worst 123gr Soft Point Grendel PPU flat based load out of 10.5" uppers, even attempting to skip mechanical firing tests and go straight to man-firing with a pre-drawn conclusion. That was all caught and nipped in the bud, but another example of the fraud that was going on behind the scenes. After the Blackwater shoot, where Grendel demonstrated superior terminal ballistics and barrier defeat (that the 6.8 guys refused to even shoot after seeing it), they went to the floor of SHOT show and started telling everyone that they can't say anything because it's classified Top Secret stuff, but SOCOM has this new cartridge that will be the next NATO service rifle cartridge and if you get in now, you'll be on the ground floor to its adoption and ahead of the competition. They went around to everyone telling them this, which was complete BS. After their spiel on the 6.8, they followed up with, "Oh, by the way. There's this other cartridge out there called 6.5 Grendel. You don't want anything to do with it because it's garbage." It was some of the best advertisement the Grendel could get. There was no hostility from anyone with Grendel, quite the opposite really. In the end, the 6.8 was banned from use overseas, all mags, ammo, and uppers were ordered to be turned in or face court martial, and one of the main proponents of it was fired from his job within a certain Army unit for committing massive fraud and concealment of resources, while attempting to use Commander signature authority without knowledge of the commander.

You can't overcome BC with velocity shooting the same projectile weight from the same case capacity. It just doesn't work out. Also, the BC on the 120gr SST for 6.8 is likely optimistic at .400, and given what we found with the 123gr 6.5mm BC vs real world, the 123gr SST BC ended up being about 90% of what was advertised. If that holds true for the shorter, fatter 120gr SST, instead of being .400 G1, it's likely in the .364 G1 region, meaning 60fps mv advantage is gone within 75yds. So much for "6.8 has the advantage out to 400yds." as if BC was asleep until an arbitrary distance. Anyone with a free ballistics program can plug in the numbers and see that there is no advantage to the 6.8 shooting the same bullet construction from the same manufacturer. 6.8 SPC 120gr SST 2460fps .364 G1 (Using a compared form factor BC that more likely represents the real world BC of the 120gr SST, vs the advertised .400 G1) 75yds 2286fps 1393ft-lbs 200yds 2013fps 1080ft-lbs 6.5 Grendel 123gr SST 2400fps .462 G1 (I handicapped the Grendel anywhere from 40-70fps from years of my 16" chrono readings just to prove the point, and used the Litz BC, not Hornady's advertised .510 G1 BC) 75yds 2264fps 1400ft-lbs 200yds 2049fps 1146ft-lbs It isn't hype or fanaticism that shows why 6.8 isn't worth it in 2018 unless you're already invested in rifles, components, or mags. It's just actual performance. The Grendel simply hits harder even within close ranges, doesn't deflect as much, and does everything a 6.8 will do and more in a tropical hunting setting, then turns around and makes it so you don't want to shoot your .308 anymore on targets. Those are very real performance advantages that carry weight when someone is considering what cartridge to go with. It's nothing personal, nothing emotional. Just hard reality that a lot of guys have to learn or refuse to learn because there was some seriously unethical marketing hype and fraud going on with the early promotion of the 6.8 to get a foothold. |

Let's be accurate with our language. -Stooxie Again, the whole history of the 6.8 has been a monstrous abortion from start-to-present in how it was handled. |

Do you guys remember all the hype about how the 6.8 would replace 5.56 in the US military and NATO would probably switch to it too?

The .270 bore was the .40 before the .40 was the .40......and answer in search of a question.

View Quote The personalities and claims sounded like those of a run out of town drunkard who was experiencing brief moments of sobriety, so I waited for 5 years to let all the beta-testing happen and bugs to work out. Keep in mind I was helping guys build their early 6.8x43 Murray chambered and DMR chambered uppers before going down range, when they were still saying it feeds and functions fine from standard 5.56 mags, which was alarming to me because I could see that they didn't work. Dudes were talking about tweaking the mags, as I looked at them and asked, "You're taking this to combat?" Their response: "5.56 gets people KILLED! Not enough stopping power." I had just got back from deployment myself and saw plenty of dudes wrecked from 5.56, as I had in other theaters before dating back several years. I can have any upper, rifle, carbine, etc. that I want. I can build and spec out a quality carbine however I want. So why didn't I jump on the 6.8? |

Quoted: A bunch a well considered, very meaningful shit. View Quote The 6.8 SPC exist now. If they ever make a Marvel superhero movie about it, I'm sure it's backstory will be most interesting. Feelings aside, an object comparison finds: The 6.8 SPC works best with lighter weight bullets and is less flexible in projectile selection due to case length and magazine restrictions. Neither cartridge is significantly more powerful than the other, nor has any special terminal effect. They are in the same class and with bullets designed to work with their respective properties there is little one can do that the other can't replicate at realistic ranges. The 6.5 can retain enough velocity to make a meaningful difference past 300 yards. How meaningful is debatable. The 6.5 is more difficult to make feed reliably. 15 years in and there there is no mag larger than the 17 round elanders that isn't a crapshoot. The 6.5 can be loaded from the magazine so that it has 700 yards before it's projectile slows into transonic range. This is nothing to sneeze at, but it is a capability that 87% of Grendel owners will never use. The longer heavier and more efficient a bullet is, the slower it comes out of the of your Grendel barrel. The medium and heavy bullet loads in the Grendel are slow enough that it negatively effects the trajectory in the in more useful 0-300y range. When you strip out all the hyperbole, the feels and other nonsense, you can see that both cartridges are a series of trade offs to shoehorn them into the restrictive AR15 magazine well. In choosing either you simple chose the set if trade offs you can live with. |

Prepare for this to go 10 pages with the clash of cartridges.
OP, here's my take on it (current 6.8 owner/hunter and future 6.5G owner/hunter): at your typical max hunting distances game will not experience any difference between a 6.8 or a 6.5 hitting them. Now, I consider about 300 yards the "typical" envelope for hunting, and if you're going to shoot out past that I'm assuming you will do enough research and have enough time behind a gun that you can answer your own questions as to which cartridge is right for you. |

With that same 12" Grendel, I take it to 800yds and engage steel like it's boring, with a 1-4x scope. https://i1085.photobucket.com/albums/j422/LRRPF52/20180717_171341_zpskpjrveit.jpg http://i1085.photobucket.com/albums/j422/LRRPF52/65%20Grendel%20Reloading/20180727_113305_zpsyjkthkn0.jpg View Quote |
