Go with the Creedmore. Brass and ammo for the .260 and the Mag are difficult to obtain.
While you are at it, stock up on LOTS of brass for the Creedmore. It may quickly fall from favor as the 'gun de jour' as the .260. For the time being, brass and ammo are available for the Creedmore.

If you reload, brass for the 260 is as simple as resizing 308, 7mm-08 or even 243 brass. Just one trip through the full length resizing die for most brass. Some military 7.62 brass needed neck turning for my Shilen 260 barrel though.
If you don't reload, 6.5CM is the way I'd go I the 6.5mm world.

Do you realize the 6.5 Creedmoor has been on the market for nearly 10 years? It came out in 2007,and it's not going to suddenly disappear from the market.
I shoot the 6.5 Creedmoor,260 Remington,and have a 260 AI barrel just waiting for an action to install it on.
Brass is easy to find or make for either one. I resize 243 brass for my 260,and you can resize and fire form 22-250 brass into 6.5 Creedmoor easier than trying to form it from the 308 Winchester family of brass.

The .260 Rem is a great choice for short action Rem. I have three .260's made up that way now and am delighted with performance. As pointed out in earlier posts, it's a simple matter to make .260 brass from other cases. But why bother when top notch .260 brass is now made by Lapua.(See attached photo) It doesn't get any better. And despite rumors spread by the usual KNTTKN's Remington .260 brass is fine. The current NRA High Power course record was set by a shooter using a .260 with handloads in Remington brass.

6.5x47 Lapua will use the same bolt face as the .308 and you can use the same magazine, which is great because you can seat the 6.5x47 right out to the lands and still be well within the magazine size so you don't have to single feed. Therefore, this calibre will work great in small action rifles.
6.5x47 use small rifle primers, but it's recommended to use small rifle magnum primers as the primers can get pierced quite easily. Also, this calibre is a nice compromise on performance and barrel life. You get less velocity for the same bullet weight compared to 6.5x284 and 6.5CM but the barrel lasts quite a bit longer. Unfortunately, the brass is expensive as only Lapua make it and factory ammo is also expensive so it'll be for handloaders only.

260 Rem brass is more readily available than 6.5 CM, and the magazines are the SAME! Ammo in .260 Rem is also more readily available, as it's got a much larger user base. I'm not sure where you get your information from, but it's clear you're in no position to be offering advice.

.260 Remington has more readily available hunting ammo, but .6.5 Creedmoor has much better match offerings. The 140 ELD load shoots well in most chambers (some even give a surprisingly low ES) and is cheap, and is completely competitive for PRS type shooting.

For a handloader wanting to shoot long range. IMO is 600+ yards then the cartridge you should definitely look at is the .260 Rem or even the .260 AI. The 6.5 CM is an excellent cartridge but it just doesn't have the brass quality that is available in the .260 flavor.
Get yourself some Lapua .260 Rem brass and some 140gr ELD's push them with H4350 and you'll have yourself a 1000 yard cartridge.
You could also do the same above and just fire form to the .260 AI and pick up another 150fps from the same barrel length. For a strictly LR shooting bench gun I'd go no shorter than 24"

perfect cartridge is
30-40* shoulder
longer neck
short enough body that it allows you to seat the bullet out farther and still be magazine fed
small rifle primers
several sources of brass, at least one of which is really good
several sources of factory ammo
the 6.5cm has the right neck and body, but the wrong brass and primer pocket. decent ammo is available from a couple sources
the 260rem has the wrong neck and body and primer pocket, but the right brass. decent ammo used to be available from a couple sources
the 260ai fixes the body and gives you an extra 100+ fps. wildcat, so no factory ammo
the 6.5x47L has the right neck and body and brass and primer pocket, but it's short so velocity is 2750-2830 range. ammo only from lapua afaik
none of them have sufficient factory ammo available at a reasonable price.
net, there's no perfect answer, so pick your poison

What's your objection to Nosler brass for 6.5CM?
I'd say there's nothing wrong with the brass, the primer type doesn't matter (or there's even a slight edge for large rifle) and 6.5CM has all the boxes ticked.

I'd just love to hear what's wrong with the primers in my 6.5CM. This should be good 
I can't really see asking for premium brass on one hand, and then complaining it's expensive on the other. I agree Nosler hasn't been able to keep up although I've managed to get enough. In the long run the fact that their run sold out is a good thing as it means they're making money and will stick around.

I'm not claiming to be an expert on the topic or anything but I have burnt out 13 barrels of 260ai 260rem and 6.5x47 mostly in competitions. Most people think small rifle primers are more consistent and that is why lapua came out with 308win Palma brass that uses small rifle primer pockets.
The reason I prefer them is the extra brass keeps the primer pockets tighter and handles pressure better. Even using the best brass in 260 I would have loose primer pockets by the 3rd or 4th round and some would be finger tight after more firings. I have 6 firings on most of my 6.5x47 now and every single pocket feels just like it did when they were new. There's no variation.
So if you had 6.5cm brass with small pockets you would be able to run it faster.
I'm fairly confident that we will be seeing some 6cm with small pockets in the near future.
Lapua brass is only $0.90 so you can get good brass without paying a 40% premium.

I have a bud who chambered his short action M700 in 6.5 X 55 Swede. I checked in my short action M70, you can get the thing in the port, it is a little long for the magazine but you can press the top round into the magazine, just the bullet is on the feed ramp. It will feed, extract, and eject the fired round. I have been thinking of doing this as you can get the same velocity but with less pressure with the 6.5 X 55 Swede.
But, I do think the best course of action is the 6.5 Creedmore round for a short action.

In above post Mr. Taliv makes the following announcements:
"the 6.5cm has the right neck" & "the 260rem has the wrong neck"
These are interesting comments and deserve further observation about the differences between right and wrong necks. Hopefully, further, and more detailed, explanation will be forthcoming.

FWIW, there's a guy on another forum selling new lapua palma brass formed to 6.5 (and 6) creedmoor. I believe he's using a hydrolic method to blow the shoulders out to creed sped, but don't hold me to that. Too pricey for me, so I shoot hornady.
slamfire some of my friends are running the 6.5 swedemoor, which is like an ackley improved 6.5 swede in their regular short action guns. it works great. lapua brass is usually in stock in 6.5 swede and it's by far the cheapest lapua brass i've seen. contact kevin at accuracy addiction if you're interested. he has the reamer and is a good dude, though he calls it the 6.5 addiction.
offhand, there are a lot of debates about "inherent accuracy" and the like, and i'm not going to get into it. i'll just say if you look at military cartridges like the 223, 308, they have 20* shoulders and short necks. if you compare them to cartridges designed for benchrest, like the 6BR, you'll find 30-40* shoulders and long necks.
in both cases, it's safe to assume they made their decisions for different reasons. the former used short, light bullets, and needed reliable feeding and longer barrel life, with no regard for reuse of brass or handloading activities like chasing the lands. the latter is more overbore and was designed to allow flexibility in seating depth with long VLD bullets, without having the base of the bullet pushed past the shoulder.

I've had good luck in terms of velocity spread and reliable powder burn on 6.5CM. The point about primer pocket wear is well taken. But personally it's not even close to a deciding factor. I deal with large primers on nearly everything I shoot except for .223 which I don't load for. There's nothing that I know of specially bad about the large primers on 6.5CM.
I don't own either, but have been looking into it. This is where my research has led.
If buying an off the shelf rifle 6.5 credmoor would be my choice based on barrel twist. If putting together a custom where you can specify barrel twist makes the 260 a virtual tie in my opinion.
If I were buying right now, I'd probably go with the Creedmoor, but the ability to make brass from readily available 308 sure is appealing and that fact keeps the 260 in the running for me.

Lapua brass available was the deciding factor for me and my DPMS pattern AR-10 build which I why I chose .260
Just fyi lapua brass might be interesting in a factory ar10 chamber. Lapua necks on 260 are notoriously thick. Lots of people wind up neck turning.
If you get any feeding problems or pressure when it gets dirty pay attention and dnf blow yourself up
But the factory gas gun chamber might be big enough that it fits pretty well and shoots accurately

Taliv Thanks for the tip. I've got a dummy round with the Lapua brass and the neck is .0003 thicker than the 7mm-08 brass I necked down. It's .002 thicker than the Rem .243 brass I necked up.
I can't say for sure as I don't have the barrel, but it will be an aftermarket barrel from X-Caliber. I'll be sure to tell them it's a gas gun and make sure they don't use a tight neck reamer meant for a bolt gun.
