Between these two cartridges, are the barrel wear characteristics similar?
 
I'd guess that more CM barrels ware out faster than .260, simply because the pressure spec is higher, and I'd bet more people hotrod the creedmoor than the .260.

Enough faster to actually notice or matter, probably not. It certainly wouldn't be one of the considerations on my list when comparing the two.
 
2,000 higher psi vs. 5% more powder... the difference in barrel life between two will be less than the statistical noise between two barrels of either.

If we’re counting angels, I’d bet on the 260 having ~200 rounds lesser barrel life than the 6.5 creed.
 
Going just on popularity, I wonder if anyone's actually shot enough .260 to require a barrel change?
 
I'd say flip a coin. Supposedly the neck length on the 6.5 offers a barrel saving advantage, but I can't really say. I'd say it's a wash in terms of barrel life from a practical stand point.

Shoot either and replace as needed.

Ive used both cartidges and used the same components, minus brass of course, and got pretty much the same velocity from similar barrel lengths.

I do like that I can make 260 brass from all the 308 and similar cases, though there are annoying issues to deal with there sometimes.
 
6 & Half Dozen! Shoulder of the CM theoretically gives a slight increase, although increased pressure and compressed powder loads to match 260 velocity, add to throat erosion..So.. its a wash. I’ve stuck with the 260 because I already had dies, load data & an endless supply of super cheap, LC brass. Anyway, if I was looking to switch up at this point, I’d go 260 Terminator, or perhaps a 6.5 SLR Like an “improved“ AI. 140gr at a solid 3000fps.

I continue telling people though....if you are a factory ammo shooter, go with 6.5CM. Can’t touch the selection. I’m a reloader. My 260 even has never eaten a single factory cartridge.
 
I logged 1,693 jacketed rounds through my 260 sporter (most were 140 gr BTHPM over 40.8 gr IMR4831). While there was some erosion, it only allowed me to chase the lands and add more powder. Since I'm more interested in blasting steel I have since switched to cast and don't worry about it anymore, but the cost of jacketed bullets alone negate any cost with replacing the barrel. The selection on .264 jacketed bullets is awesome but at an average of .30/bullet its a money hole. A very fun and addicting money hole.
 
some of us old farts found out years ago about a 6.5 that started out in 1896, before the 6.cm-260 rem were thought of. the 6.5x55 swede, my cz 550 will get 2800+ fps with N-560 with any 140 gr bullet and 3000+ fps with any 120 gr bullet with the same N-560. i know the action is a little longer adding a few more oz,s to the over weight. my rem 700 classic in 6.5x55 with do the same thing with N-560.
 
Agreed, my 6.5x55 Swede was my first 6.5 and it's one of my favorites. I also own a 260 Rem and a 6.5-300 Wby Mag. I quit trying to justify gaps and needs years ago. Now I just buy what I like and enjoy when time and $ permit.
 
I agree! The Swede was WAY ahead of it time! Great long range cartridge, and designed with a more MODERN “target cartridge friendly” 25* shoulder. While researching to build my bench rig, the 6.5Swede was my chosen cartridge. However, after deciding I wanted a short action & ability to feed via 10rd AICS mags, I ended up going 260.
