I am looking to rebarrel my 308 to one of these calibers. I will be using it for deer hunting, coyote hunting and target shooting out to possibly 800 yards. Does anyone see any advantage of one over the other for my intended purpose? I plan to go with a 24" to 26" barrel.

Either is GTG, and a big step up from the 308 in terms of ballistics. That said I reeeeally like the 6x47L. I run 115s @ 3050 in my 27" comp rifle. Insanely accurate, great ballistics, low recoil. Not to mention the Lapua brass is incredible!
Downsides to the 6mm version are-
Shorter bbl life .
Less energy on target.

i've got both. Although my 6x47 is set for the lighter bullets - 70 to 90 gr. Both are very accurate. The 6x47 is my P-dog gun, flat shooting out to 400yds with the 70 Blitz and my 6.5L is good out to 1200 or so using 123 Lapuas. The 2 compliment each other perfectly.
What he said. I like the 6.5 for competition also and better barrel life when compared with 6-47.
Agreed. I've dropped some pretty big hogs with a 243. Run the ballistics through a program to compare down range energy at the distances you plan to be taking the shot.
My 6.5 dropped a 160 pound 8 point where he stood at 430 yards with a 130 grain VLD. It was almost like a bad video game how he just dropped. Te greatest thing about the clambering to me is the barrel life you get for the ballistics it produces. A 6 might be good, but you're gonna loose that characteristic. So if your gonna shoot it a lot, I would go with the parent cartridge.
I have a 6.5x47L and really like it! That being said, I am leaning towards the 6mm for my next rifle
I have a 6x47 Swiss Match (not the same thing) and a 6.5x47 that I recently sold.
I personally wouldn't build a 6x47 when you can build a 6mm XC and use Norma brass. And I would not build a 6mmx47 Swiss Match as brass is a pain in the ass to get from Europe.
Honestly I'd build a 243 Win and shoot match brass out of it. When it comes time for me to set back the 6x47 SM it's going to be a shiney new 243 Win bore.
I don't have a lot of love over the 6.5x47 Lapua either, in the testing I have done on 3 barrels, I have found it to have more vertical dispersion at 600+ meters than the 243 and 6mm XC do.
A friend of mine is having great luck with the 6.5x55 Ackley improved.
Lots of people have more experience with the Swiss Match, XC, 6mmx47 Lapua, 6.5x47 Lapua and other sniper/match cartridges than I do. I have about 1500 rounds out of the Swiss Match and 6.5x47 put together.
Remember the confusing realm of rifle cartridges dictates that you really need to do your homework on them.
There is more than one 6mmx47 anything.
If you build it and have faith in it, then give it a shot.
Barrels are cheap.

What's the consensus on the 260 AI? It seems like 6.5 is the way to go for deer but I think I want a little more velocity than the x47 can provide. Thanks for everyone's responses.

The real question is, how far are you planning on trying to take a deer? Have you looked into a 6.5x06? It wouldn't be the best target round out there, but would rule hunting.
I think 600 would be my max for taking a deer. But I will be target shooting farther than that. I can't go 6.5-06 because I am working off of a short action.

Was kind of a dumbass suggestion, I had read .308! Either a 6 or 6.5 x 47 will cleanly take a deer at 600 if you do your part. I like 6.5, on my third one. I shoot against a guy with 6's, it's a wash to 800 on targets, then the 6.5 will rule.
But on the other hand, the top shooter in the country is shooting a 6x47, or was last year, and I'm sure the targets didn't stop at 800!

I have both and like both. I believe the 6 X 47 has an edge at distance. With 105 Bergers and RE 17 it's hard to beat. I get 3300 + fps out of that combination. Pretty spectacular ballistics. More foot lbs of energy continually after 200 yds than a 308 with 175 grain match kings. In our local dynamite shoot, dynamite in pop cans, I have several hits at 1200 yards, that's pretty good accuracy. Barrel life is about 2200 rounds. Certainly good enough for any mule deer with the right bullet.

G'day all,
What sorta vertical are you guns with 6x47L getting at 600-1000yds? I have just bought a 6x47L F-Open rig but will also be running in in the bush for taking ferals. Do you find your 6mm holds better vertical then the 6.5mm?
Cheers guys.

800Y is a easy for both. For coyotes the 6 would be more appropriate. 105's near 3100 fps with H-4350 or H-4831 is doable and would put a deer down fine. Both are excellent cartridges.
The smallest 1000Y group I've ever shot was with a RFD benchrest rifle in 6x47L. 5 shots that were 3.5" wide with less than 2" vertical.
Thanks, just a lucky day. I sold the rifle years ago. Something like 105 Berger VLD's at 3080 fps with N-160.
Jack,
Somewhere around 2000 for the 6 and 3000 for the 6.5.
The two 6x47 barrels I've had burn out went from 1/2moa to 2.25 moa the next day at the same match, one year apart and discovered on the same stage. What are the chances??? !@#$%^&*()
First barrel had 2400 through it and second had 1500. The 3rd, which is melonited, has about 2500 through it.

Steve,
That's good news as the load that my new rifle is shooting well with is running at 3100 and not flat out so should get life around the 1500 mark then hopefully. Thanks very much for your advice.

6.5x47L
Hmmmm...I kinda like my 6.5x47L! Jon Beanland knows how to build a rifle!!

I do, very little throat erosion, If I make it to 4000 I'll really be impressed.
6.5x47 gets my vote for your purposes. The extra bullet weight will help with hunting and spotting hits.
Preliminary for me, but no, I don't believe so. It does give a slight reduction in muzzle velocity, as it is slipperier than stainless, but I get great groupings even though I am not the world's greatest marksman.
Why would the lower coefficient of friction from the melonite treatment decrease muzzle velocity? That's counterintuitive.
Joe

Because a certain portion of muzzle velocity is dependent on the friction that is in the barrel. Friction in the barrel is what allows the pressure to grow, and higher pressure creates higher muzzle velocity---not sure I am explaining it right. Anyway, if you do your research well, you will see that the published claims are that MV is reduced by close to 50FPS. You can probably regain some, maybe most of that back again in load workups, as the peak pressure is reduced in a melonited barrel, so your individual rifle max pressure would be lower, allowing you to increase powder safely to probably regain the lost MV. Unfortunately, I can't give you real world numbers to show all of this, because my barrel was melonited before it was ever shot, thus taking away the comparison ability. The factory barrel was a Rem 700P 338LM barrel at I think 25" plus brake, but the new one is 34", so we cannot compare there either.
