    For those wanting to hunt med size game to eat, then sticking with well designed non-fragmenting projectiles (typically bonded or monolithic) is best.

    In .223/5.56 mm for hunting deer and hogs under 200-300, go with bullets like the Fed TBBC, Speer Gold Dot (or identical Fed Fusion), Nosler/Win Bonded, Nosler Partition, Rem CLUB, Swift Scirocco, Barnes TSX/TTSX, and Hornady GMX.

    6.8 mm is great for deer and hogs out to 300 or so, again using bonded or monolithic projectiles.

    6.5G works for going longer using an AR15, with the limitations discussed by SLG.

    For larger game like elk, I prefer a .260 Rem/6.5C, .308, .30-06.

    In a bolt gun, I find no reason to go with .223. .300 BLK, 6.8, 6.5G and stick with calibers with more case capacity like .260 Rem/6.5C, .308, .30-06.

    Anyone who can build a high quality AR can put one together, no doubt.

    My one stop shop today would be Precision Firearms.

    1) thoughts on 6.5 Grendel vs 6.5 Creedmoor as hunting cartridges in the AR platform?

    2) with over two dozen elk, caribou, moose and mule deer in the mountain west and Alaska, I am very partial to .270 and .300 magnum cartridges for these animals, for power and flat trajectory.
    Likes pretty much everything in every caliber.

    Doc - since you have joined in this thread, thanks! - do you have any insights as to why the designers of the 6.8SPC went with .277 (6.8) bore size versus .264 (6.5)? There are some AR wildcats using 6.5 projectiles in 6.8 cases now trying to get the "best" of both - avoiding the bolt issues of the 6.5G while using the 6.8 case but using 6.5 projectiles to get the better BC.

    1) I will comment. Again, the 6.5 Grendel excels as the "best" cartridge constrained by the AR platform. If you want to hunt and you restrict yourself to the AR platform - it is the best thing going - IMHO. The 6.5G is outclassed by the 6.5CM because of the extra powder capacity and therefore velocity.

    2) I do not like recoil - there, I said it. I like the 260 and 6.5CM as best compromise for ME for lethality versus recoil. I do not like magnum recoil. 270 is excellent - what would be really interesting to me would be the 6.5-06 based on a 270/30-06 necked down to 6.5 but I do not want to go down the custom rifle path. 6.5 Creedmoor in the Hornady Superformance load with 120 GMX is good enough for me.

    There's just too much more power in the 6.5CM due to case capacity. Now, if you start prioritizing "light and more packable" and are judicious about your shots, the 6.5G could work. Also, if you want to swap in between say a .204Ruger upper or .223 upper for varminting and then to 6.5G for medium range hunting, that would be convenient. The same for a thumper like .300Blk or .50 Beowulf and then switch over to the 6.5G for medium range hunting.

    Here is some data comparing the 6.5G, 6.5C and .300 WM.

    velocity and energy at 300 and 400 yards, all with 24 inch barrel which is quite long for the 6.5G and C, but that is what Hornady showed:

    6.5G at 300 yards, 2,090fps/1,193 ft-pounds at 400 yards, 1,940 fps/1,028 ft-pounds
    6.5C at 300 yards, 2,330 fps/1,446 ft-pounds. at 400 yards, 2,148 fps/1,230 ft-pounds
    .300WM at 300 yards, 2546 fps/ 2,589 ft-pounds. at 400 yards, 2,366 fps/2,238 ft-pounds

    Drop at 300 and 400 yards with a 200 yard zero:

    6.5G 8.70 and 25.30 inches
    6.5C 7.10 and 20.60 inches
    .300 5.90 and 17.30 inches

    No surprises. Different applications, different niches.

    "do you have any insights as to why the designers of the 6.8SPC went with .277 (6.8) bore size versus .264 (6.5)?"
    Uh...because it worked better for the requirements.

    There is a lot of misinformation regarding 6.8 mm SPC development, for example this flawed article: http://www.thefirearmblog.com/blog/2...-the-6-8mm-spc

    This is a better article, but still not perfect: http://demigodllc.com/articles/6.8-m...g-arms-carbine

    Keep in mind I was there at the original terminal performance testing of 6.8 mm and still retain much of the email and lab data from those initial test sessions in early 2002. By the time I got involved, the original designers of 6.8 mm SPC--Steve Holland of 5th SFG(A) and Cris Murray at AMU, as well as Troy Lawton of AMU had already tried a 6 mm PPC case necked up to 6.5 mm and had too many reliability issues in AR15 variants. They then went with a modified .30 Rem case in several calibers--those are what we began testing in the Spring and Summer of 2002, with the first results being discussed at the USSOCOM M4 SOPMOD OCONUS Review at Ft. Campbell in Aug of 2002. At the first round of testing, there was no 6.8 variant. The 6 mm versions did not do well against intermediate barriers and the 7.62 mm version did not offer anything better than 7.62x39 mm. The 6.5mm bullets showed the best accuracy and the 7mm bullets were the most destructive. I may still even have some of those early SPC cartridges left with the 6.5 SPC and 7 mm SPC headstamps. A month later, we tested a 6.8 mm compromise variant--the 0.277" bullets showed nearly the same accuracy as the 6.5 mm version and almost as good terminal performance of the 7mm, thus the 6.8 mm SPC was born.

    Scopes for the 6.5G.

    Any good scope will work, if it is suitable for your intended use. As you can see from my pics, that means NF for me. Specifically, the 2.5-10. It may be the single scope to rule them all, if I could only have one scope to do everything I want.

    On the 6.5, it offers excellent low light ability and illumination for hunting. Excellent tracking for repeatable precision. Ruggedness in a reasonable weight. Good reticles that you can bias towards hunting or precision shooting. An easy to use zero stop:-)

    For me, it is perfect for the purpose, but other scopes are fine as well. Just depends on what you want to be able to do. The NF allows me to do anything I want with the G, which is how it should be.
