I had a 6.5 Grendel at one time. Just trying to figure out if I want to go down the same route. Give me the pro and cons of the 6.8.
I don't think anyone answered this question. Biggest pro in favor of the 6.8 is bolt life. Research AR15 performance and look at the 6.8 forum. eye opening and interesting. I have one of their 3r barrels in 6.8.

To be honest, I have;
3- 6.5 Grendel's (had 5 at one time)
3- 7.62x39 (had 4 different ones over the years)
1- 6MMS ARC
1- 5.56 (can't even begin to tell you how many over the years)
1- 300BO (had 2 more but gave them to son-in-laws)
3- 6.8 but they are all gone (gave them to my son-in-laws)

So far...zero broken bolts.
My next range trip I will most likely break one, but to date none!

I dont do any high rate of fire, but I do shoot them a lot...A LOT! When I go to range I will have two AR's with me. When reloading supplies were more stable, I used the go once a week. I've cut back to once a month.

Hunt nearly exclusively with my 7.62x39 AR and my wife hunts with a 6.5 Grendel about 50% of the time.

I feel the bolt issue was poor design, I know both the 7.62x39 and 6.5 Grendel had bolt issues early in their inception, but I'm pretty sure it not very common any more.

Love my 6.5 Grendel! All my shots are 150 yards or less and 90% are head shots during the daytime. Night hunting rig is a 556 with thermal but here you get much closer at night so it seems to work just fine.

I shoot the 90gr GD and it is deadly. 18" ARP.

Even my ex-jarhead buddy that shoots LaRue rigs for the DOD loved the rig.

that they are, i took an 8 pointer with a 90gr GD, he only ran 5 yards but no blood trail.

my 110gr accubond load, well the only one i had run left a blood trail Ray Charles coulda followed

300 HAM'R from Wilson Combat. .223 bolt, superb groups, super lightweight. This is the answer to nearly every 15 platform question :cool:

I've killed plenty of hogs with a 22wm, so if caliber or cartridge is in question.... don't question it! 300 ultimate hog hunter is just marketing plain and simple! Using the old 5.56 55gr fmj for more ammo without reloading is my 2nd option. In an AR-15 I have 5.56, 6.5gren, 6.8spc and 300bo and 1 us just as good as the other within 300 yards. Shooting farther the 300bo with less than a 16" barrel and 150gr bullets, 1 of the first 3 might be a better choice. All if the dead piggies died from a fmj. I do live my 26cal (6.5 Gren, 6.5CM, 260Rem and 264wm), but favor the 6.8spc2 in an AR-15.
