6.5 CM 100.0000000000000000%
The ammo sells out fast for a reason.
The ammo is coming through in small drops to RFDs, I've been getting drip fed American Whitetail and having spoken to supplier and importer I know more is coming before Xmas, though you might have to phone around a bit.

I do have 6.5 cm space on ticket but gunshop put doubts in my head yesterday

@Jim 7 What type of 6.5 CM does your local gun shop have?
Bearing in mind you'll want a box for zeroing, then after that perhaps 2 shots per outing, and you'll want to stick to the same ammo to avoid re-zeroing.
Worth checking other nearby shops. I've been going to 2 different shops, 1 30min away, 1 60min away, I got my full quota of the ammo I wanted from the near one last month and again this month from the further one, despite both previously saying they don't know when their next delivery will be, and I know more is coming from Hornady on back order at both shops.

I personally wouldn’t worry about it in the medium and long term; the 6.5CM has really caught on and availability will only increase.
Conversely, ammunition for the excellent .270 may start fading out of supply due to the success of the slightly-smaller caliber.

To correct some of the earlier posts: the 6.5 Creedmoor is NOT faster at hunting distances. It’s is slower than a 308. It is slower out of the barrel.
The 6.5 is faster at long distances and has a longer supersonic range due to the more efficient bullet. But slower and less energy at short range hunting distances.
6.5 Creedmoor bullets come out slower from my 24 inch Creedmoor barrel, than 308 bullets come out of my 20 inch 308 barrel.

Thanks VSS but I'm after a left hand. I have a righthand .243 which I got a good deal on just to try stalking. 5 years later found my passion for stalking so want a true left hand now. This is why I'm stuck on calibres but cheersYour problem solved:

Depends on how hunting distance is defined, but yes, the 308 will put out bullets of a given weight at a higher muzzle velocity.
On the other hand, the milder recoil of the 6.5 tends to make for more-accurate bullet placement.

Can't remember now but I do have a couple more shops near me which I'll check with aswell

I have both. If I had to have just one, it would be the 6.5 CM. Drops deer just as dead just as quick, suffers less wind drift but the game changer for me was keeping the target in sight after the shot due to lower recoil. Nicer to shoot and plenty of ammo choice, plus as easy to load for as the 308. Where the 308 scores better is it's better for all UK quarry types from boar to lowland Reds to munty and all can be taken with one bullet, one load. My 308 150grn hunting loads exit at 2750 fps. My 140 CM loads exit at 2700fps. There's nothing in it until you reach out past 500 yds except the slight wind drift advantage of CM but for me, the ideal cal is the 6.5 due to the lower recoil.

My 6.5CM has an 18" barrel and I use Winchester Deer Season XP 125g.
On the box it says 2850fps, on the chrono it says 2668fps. I zero at 175y and Strelok Pro says that between 50y & 200y I get a total rise and fall of 2.1 inches, which seems right from the results I have had.
It is so nice to shoot and so wonderfully accurate that I also take it foxing with my thermal fitted when the ground dictates.
I did get told by people who know what they are talking about, that the faster twist rate of the 6.5CM is better suited to copper ammo. I just know it is accurate with that stuff to.
Never having owned a .308 I can not comment on its performance, however, either round will drop deer, choose the rifle you are happy with and fits you best and enjoy your hunting.

For sure. Of course 6.5 can be used with a sub-20” barrel, but I probably overvalue efficiency, so running one would leave too much MV/energy on the table for me.
Conversely, the increased cross-section of the .308 is more effective at getting a bullet of comparable mass up to speed in a short distance, so I find it’s a more elegant solution.
Though I suppose a bigger factor is that I simply like having a justification to put together another rifle.

CM really needs a 24 inch barrel to make the most of efficiency for most loads. 18 inch will rob a good 125 to 150fps or more as you've found Phil. At deer distances it probably doesn't matter much except you lose some hydrostatic shock value with lower terminal velocities. There is argument amongst some scientists that pressure waves don't contribute to shock which is governed by temporary wound cavity. A separate topic, I know but one some might consider when looking at bullet choice. The balance of scientific data and experimentation points towards the rate of expansion and temporary wound cavity being both major contributing factors in energy transfer which can cause sufficient hydrostatic shock in shots near the CNS to rupture blood vessels in the brain, and the combination of this and localised wound cavity energy transfer to vital organs resulting in bang-flops. So with a shorter barrel, and less terminal velocity, bullet choice arguably becomes more critical. @dodgyknees posted something about shock value a few years back with some interesting info on HILAR.

I am with you Bob
Light weapon with a short barrell, delivering an accurate shot for a clean kill, wins for me every time. The figures show that I am still getting 1536 ft-lbs at 200y, that will do it.
There are so many elements that make shooting the wonderful sport it is, and many of us take our joy from the fine tuning of a weapon and the rounds to go with it.
For me, its once I have found the right combination and have set it up, my pleasure is hunting. Thats not to say the other bloke is wrong, far from it. The more people involved in a broad spectrum of shooting disciplines, the better it is for sport. We all need to recognise the value of the other bloke, maybe take the ****, but still support him and all stand together against the anti shooting mob.

As to ammunition, harmonics vary from barrel to barrel. You need to find what works best in yours and then see if you can buy it locally. As gun shops pack up its only going to get more difficult.
I am sure that those who home load can get round this, but for those that don’t.
I believe a lot of these new calibres will come and go and are just a way of helping manufacturers sell stuff.
You have to be pretty good to outshoot a decent factory rife (Tikka for example) which has been properly set up with decent optics and the right ammunition.
