So which one in the right hands is the best so far for tactical style competitions out to 1000 yards. On steel and paper with a barrel 22" or less so it is maneuverable around barricades and other obstacles. I'm not looking for a best on hands down don't buy anything else. Just what those who have been running them's thoughts or regrets on their decision. And maybe what they would do different. Also which bullets used and velocities or mils to yards.
6 CM, 6.5 CM or 260 AR comp gun out to 1000

all three, really with copper creek, mccourt, and southwest you can get 260, 6.5 or 6 already loaded. hornandy makes great 6.5 factory ammo. its really whatever you feel like running, i know most of the GAP boys are running 6's while surgeon is running 6.5 or 260 from what i remember.
I'm running a Mega MKM key mod with a 20" Lilja barrel. It's a freakin laser beam and recoils like an AR15. I have an AR gold trigger in it which is sweet. I feel I am good to go to 1k no sweat. I'm shooting 123 A-Max, 142 SMK and Berger 140 BTLR out of Remington and Lapua cases with either H4350, 4831 or RE19 and CCI BR2 primers. The best loads for me are just under max. Just love it!
1k no problem with 6.5 Creedmoor in my stock DPMS. Long range is very, very new to me, but the cm really appears to be very consistent ammo from Hornady, and the reloads that I have used have been just slightly better. I've been using the 140 A-Max's from Hornady mostly. My friend was making up reloads with 142gr SMK's. Both were very good. His were slightly better. I don't have data to suggest how much better. Would be slight. I haven't noticed a difference between lot numbers on the Hornady ammo. I'm using a stock 24" DPMS bull barrel. Will be moving into a 26" Kreiger barrel for this year.
If by 6CM you mean 6 Creedmoor (and not 6 Competition Match), I will tell you that I am loving mine so far. I am sure all will get the job done, but running that 105 up around 3050-3100-ish is a pretty nice way of doing it. I am just getting started with mine, and others here have far more experience, but my choice was/is the 6 Creed.
Show up at match with a semi, a bolt gunner is beat you, and by a wide margin, but if your heart is set on competing with a SA, go 6.5 Creedmoor, reason why is the cartridge is shorter than 260Rem, and chasing the lands will be easier with the 2.810ish mag limitation.
6.5 Creedmoor because of above mentioned reasons. Plus 6cm excels at higher velocities and many matches are limiting their velocity close to where the 6mms do better. Shorter barrel will also favor heavier bullets.

If you reload, .260 Remington offers way more brass options/sources. I have no issues with the VLD projectiles from Berger, Lapua, Sierra, Barnes, etc. Seating depth doesn't need to be anywhere near the lands as many shooters used to believe, and Optimal Charge Weight, Barrel Time, neck tension, and projectile/neck/chamber concentricity play much more important roles in accuracy than seating depth. Here are some very first loads with H4831 and the 139gr Scenar I tried in my .260 gas gun built by GA Precision,and those are 5-round groups at 100yds. I have groups with the 130gr Berger that are even smaller using H4350, and I load to 2.805"-2.810" COAL with the 130 VLD's.
6.5 Creedmoor is great for those who don't hand-load. I think the case design burns powder more efficiently with its shoulder angle, but the brass does not last as long as Lapua brass. The 6.5 Creedmoor is Hornady's 30TC necked down.

LOL, all depends on the shooter and rig. I've seen it go both ways. If any advantage, the semi has it due to much quicker follow up shots.
For the OP, if I build a AR10, it will be a 6.5CM due to the Hornady ammo. I don't always have time to reload...
I went shooting with a good friend of mine and his 6.5 CM in an armilite AR10 and my 260 rem bolt, we were both hitting the same targets at all distances up to 1120 yds all day.
I am now building the same 6.5 CM he has and he is building the same 260 bolt action I have.
they are both great.

Your statement is as outrageous as it is false. It suggests you have little experience with the concept. A good shooter can realize the best results with any match conditioned action type. I actually prefer an AR style firearm to a typically stocked bolt gun, as I can manage recoil resistance better, without the sort of motor memory mustering required from a bolt gun for similar results. I'm looking at a trophy right now from a Southern Indiana R & P C five hundred yard event I won back in 2000. I shot a match rifle/any, any rifle agg. of 397 and 16 with a .223 Space Gun. As I recall, I did not think my gun was a handicap while I shot the match, as I'm sure, after the smoke cleared and the dust settled, those shooting bolt guns that day did not see my AR based gun as being a handicap.

Generally speaking, I agree with all you say Sterling. It comes down to the shooter not the equipment-That is why you still see .308's at the winners tables at some events. So many rely on the equipment to compensate for the skill that is lacking-I consider myself a prime example. The one thing I will say when comparing bolt guns to AR's chambered in the same caliber is it is extremely hard to run the same velocities when comparing the two, but I consider that a wash when you consider speed in follow up shots. No upgrade in equipment will ever trump skill on the trigger.
To the OP, I recently acquired a JP LRP-07 in 6.5 Creedmoor and now understand how a truly accurate AR can perform. This chambering offers great ballistics and very affordable and accurate factory loads. You might want to take a closer look. I am taking this rifle to 1000 yds tomorrow....
5 shots at 100 yds>

I have won many LR tournaments with a bolt gun chambered for 6.5/284. Building that gun, to get the sort of velocity and sight radius I wanted, appeared to me to be easier with a bolt action I had than putting together a semi auto, which would have required some experimentation, and, why bother, since NRA LR is a single loading exercise. Also, since I saw no handicap using a bolt gun, I pursued that course. My point, as you understood it, is today's AR semi auto action type is not inherently less accurate than a bolt action type. After shooting a stock DPMS SASS recently, producing a 5 shot group which measured close to zero dispersion, I just don't think too much about action types anymore. My focus today is all about practice schedules which hasten picture and motor memory development. That's what I think is really important to good shooting.

Agreed.
BTW, I run a 284 win in a LA and love it. Hits at a mile not uncommon.
Good shooting my friend.

I am surprised that no one has yet mentioned that them260 Rem and 6.5 Creedmoor give the same ballistic performance. Of course the 6mm is different. Between the two 6.5 bores, Imwould base selection on whether you reload or not, andmwhether you already have any omponentsmfor one or the other.
although I went with the 260, the ready availability of match ammo for the creedmoor, and having the ability to duplicate factory ammo are strong selling points for the Creedmoor over the 260 Rem. Lapua brass, and ready availability of other cases that I can make into 260 Rem cases favors that case.
I don't have any experience with the 6mm CM.

Correct me if I am wrong here.
Isn't the 6mm Creedmoor to 6.5 Creedmoor as .243 Win is to 260 Rem?
So really this thread is a .243 vs .264 debate and a Creedmoor vs 308 Win case debate?
I went with 260 in a bolt gun for my purposes. I don't think I could have gone wrong with 6.5 Creedmoor either. I didn't already have any components for either, but have some 308 brass. I haven't made my own brass but the ability to do so appealed to me. I also have a friend that steered me to 260.
The reason I didn't go 6mm/243 is that there isn't as good of bullet selection of the heavier bullets. Also not many factory rifles have the twist to shoot the heavier 105-115 gr bullets.
