Hornaday has added a new round that looks like halfway between 260 and 6.5x47 Lapua. Is 6.5 gaining critical mass?

It looks like new cartridges are the gimmick of the year.
6.5 Creedmoor, .30 and .338 Ruger from Hornady; .327 Magnum from Federal. Who knows what more they will come up with in time to show off at SHOT.
I don't see the 6.5 Creedmoor breaking out in match rifles. One guy said "Hey, if it is good quality, it looks like it would be convenient to make 6XC out of."
As to 6.5 in general, I think I have heard of more 6x6.5x47 rifles than original 6.5x47.

Yep, the 6mm and 6.5's are winning all the long range matches. High BC bullets with low recoil make them very easy to shoot.
I did a preliminary try at case dimensions based on what I could find and starting with the 260 Remington. Anyone interested in the QuickDesign file PM me.

Hmm. That says you would be at a compressed load and excess pressure to reach advertised velocity, with H4350, right?

What will it do that a .260 Remington won't? I'm trying to see the point of designing the new round.

It will give Demille a proprietary cartridge made by Hornady for the T2K. This is what he wants. A caliber loaded to "match" quality that can be had from a mainstream big name company that will keeep up with the 6XC.
Now one can buy a T2K in 6.5 Creedmoor and order ammo from anyone that stocks Hornady ammo.
I've known about this for 6 months. I also knew the day before that the price of a T2K would go up 1K. I didn't act. Should have. I know the guy that bought all the remaining stock (4) for resale. There is also a company that is in the process of making a T2K knockoff. And that is all I have to say about that.
Howard
The 6.5 Creedmore apparently serves the same purpose the 6.5x47 Lapua does. It allow the loading of longer, high BC bullets in short actions without intruding into the powder space. 260 is fine for 120 and 130gn hunting bullets, but if you load something like a 142SMK or 144 Lapaua Scenar, it can get a bit tight.
I love 6.5's. Miss my old pre-64 264....but this 6.5 looks nice.... like a
P.O. Ackley improved....I always thought the 6.8 SPC (a 25 Remington up to 270) should either be 6mm or 6.5mm....
I did pick up a couple of 264's to begin again.....
140 grains at 2800 is very nice....

It's DOA as a LR cartridge for a couple of reasons:
1. It has even less performance than a .260 Rem.
2. No quality brass (Lapua) available for it.

That looks very good. How does that stack up to the 7MM-08?
7mm-08 has the same problems as 260 - no room for long, high BC bullets. For a hunting catridge, 260 would be a better pick than 6.5 Creedmore, and 7mm-08 has a small edge in energy unless you shoot the same weight in both guns, in which case, the 6.5 will generally have a BC advantage.

I'm thinking of a dedicated long range Speed Goat gun. Something specific for Antelope, Kudu and other such critters. I was thinking 7mm-08, but this sounds interesting.

I have a 6.5CM T2K barrel and some ammo. I'll be testing it, and comparing it to both 260REM and 6.5x47 here in about a week.
The idea behind the 6.5CM is to be a viable long-range cartridge with components and the factory load recipe readily available, at lower peak pressure than 6XC.
I don't think the 6.5CM will be "DOA". 260 Rem certainly doesn't have great yet affordable brass available (if you can call Lapua "affordable"-- the Nosler brass is cripplingly expensive). On the contrary, I see it as a viable alternative to the 260, with a potentially better case design and brass. The 6.5x47, 6.5CM, and 260REM all perform within spitting distance of each other, however, the 6.5x47 loads need to run at considerably higher pressure to match 260REM ballistics.

GunTech,
All us .260 shooters don't seem to be having problems shooting the 139's - 142's at 2.800. Also note that Lapua factory 338LM is seated WAY in there. It works fine. This "problem" is WAY overstated. Also note that all those 68-77gr 223 loads work the same way.

If my 260 shoots about quarter MOA with reloaded brass, shooting the 139's seated to 2.820, how would I detect this "problem"?

And, therein lies the problem and the reason that it's going nowhere. It's the solution to a problem that doesn't exist.
Don
seems like the ole' 6.5mm/08 ackley improved. just standardized and givin a cooler name. one thing though, is that case forming and fireforming is not an issue due to factory ammo. but i dont know of anyone that goes to the store before a match to pick out his ammo.

What the 6.5 Creedmoor looks like is a very nice highpower or silhouette cartridge; sufficient power, minimum recoil. It's remarkably close dimensionally to a 6.5X250, aka 260 Bobcat, though Hornady is claiming 10 grains more powder and 200 fps more velocity. Question is, what powder is Hornady using and can we get it?
The 6.5 Creedmoor isn't a 260 Remington, but that IS the point!

Nope it`s not!
To me it appears to be a shortened 260, about 0.10" in body. Sorta like the 45 acp and 45 GAP. Notice to the velocities listed for it are from 28" barrels, not 24". Aaaaaaand you still need a action capable of holding full 2.820" cartridges, the same lenght as the 260. Hmmm, still can`t see what it does that`s really new.

H4350. -- Same powder I use in 260REM.
6.5CM's taper is less than 260REM, so the case capacities are going to be almost identical.
260's problem is that there's no good but halfway affordable brass.
Brian,
It's not the same as 6.5-08AI, which has a case capacity closer to 6.5-284 or 6.5x55. 6.5CM's body is shorter than 6.5-08AI.
