I'm missing the reasoning behind this cartridge.

Is it a long range cartridge for recoil sensitive shooters? Or marketing and hype - like we saw with the short-magnums? What reason to buy a 6.5 Creedmore wouldn't be better served with more powder capacity like the 260 Remington and 6.5 Swede?
 
It is a CREEDMOOR - like the famous range.

I have several 260Rems with the Ackley mod. These are throated to take 140 gr bullets set well out, so as to not take up powder capacity.

The results is a short case with similar capacity as the 6.5x55, but the loaded round is too long for short action magazines

The result is higher performance than the Creedmoor, which gives up case capacity, so it can be used in short actions.

The 260Rem could have been made by a gun maker with a deeper throat and would easily match Creed performance, with a bit more velocity.

That said, the Creed works well.
 
Popularity means availability.
It’s basically taken the precision rifle series by storm.
Factory match grade ammo for those that doesn’t have the means to reload yet.
As stated above, in order for a 260 to be loaded long enough to take advantage of the extra case capacity, you’re into a long action, if you want mag fed.

Not really.

Comparable performance that can actually be used in a short action, mag fed repeater. It also has a longer neck and is slightly more efficient. The swede is a wicked cartridge but you do have to trim them a lot.
 
6.5 creedmoor is getting to become a readily available calibre in factory and even bulk loads.
6.5 creedmore is also a popular barrel for semi action rifles.
Less recoil and overall pretty much the same as 762 means I can practice more in a day at the range.
 
When the 6.5x55/260rem/6.5CM are all loaded to their full capacity, with modern powders in stronger modern actions, the 6.5x55 is pretty hard to beat.

I have a Tikka T3 chambered in 6.5x55 that I load to the same pressure levels as the 260rem and it does generate slightly higher velocities. I also have the same type of rifle in 260rem that is every bit as good as the Swede as far as acceptable/repeatable/consistent accuracy goes.

I wouldn't want to have to make the choice between them. I have a 45 year affair going on with the Swede so I defer to that round.

The nice thing about the 6.5CM is lower recoil, and less throat wear, which is important when loading for a competition rifle. That doesn't mean the round isn't an excellent hunting round.

Even the little 6.5 Grendel has its place in the field IMHO. It's a great little round that outperforms for its size.

When shooting the 6.5 family of cartridges, off the shelf ammo MIGHT BE ACCEPTABLE. This group of cartridges definitely responds very positively to experimentation and hand loading.

I had a co-worker try convince me that his 6.5 Creedmoor can match the ballistics of my 300 WM. Try again, buddy. A 6.5-284 in a long action will do it but not the Creedmoor. In a short action I'd go with a 6mm Creedmoor for competitive shooting. With a 1:8 to 1:7 twist barrel it will beat the 6.5 on trajectory. But I'm a speed junkie so a 243 Ackley Improved is more tempting.
 
Its a jack of all trades cartridge. Inherently kinda accurate, throws a .66 bc projectile at 2700 - 2800 fps (300 winmag throws a .69 at 2700 - 2800), fairly light recoiling, its big enough to hunt a lot of stuff, and you can find in factory loads most anywhere now which is the biggest plus for most, and fits all that into a SA or ar10 clone.
If you are looking at the competition scene and can reload go with a 6mm, switch out 243 and 243 ai for 6 super lr, better design.

For some loads the 6.5mm Creedmoor is capable of duplicating the muzzle velocity[2] or trajectory[9] of the .300 Winchester Magnum while generating significantly lower recoil, based on lighter projectile weight.

.260 Rem will out perform the Creed with lighter bullets; the 6.5 x 55 will outperform it with heavier bullets. 6.5 x 55 brass is proprietary, and can not be made from, or into anything else (it's only draw-back). It is renowned for it's accuracy too.

Creedmore? Really, what is the point?

Works VERY well in Short actions such as M7 Remmy as the Bullets can be seated out so more powder capacity and Less case stretch then the 260 Rem or the 6.5 x 55 Swede ! Not saying its any better BUT it is a GREAT cartridge ! And YES i do have a Rem 260 and 6.6 x55 Swede too :d I LIKE them ALL ! RJ

Trajectory and muzzle velocity does not equal ballistics, it’s only going to match those with a lighter bullet. I imagine you know that tho.

Actually that is external ballistics.

Here are charts with the same environmentals for both and also the highest bc loads hornady makes for each 300 win and 6.5 creed. Both start speeds are 24" barrels.

As you can see drop is very similar. Creed wins it in wind drift. Creed actually passes the 300 in speed.
Target energy goes to the win mag.
