Should I go 260 Rem?

As has been said they really are pretty equal. Especially since you now have Hornady, Berger and soon Prime .260 factory ammo options that are all great. But I agree with not needing both. I happily went 260 because I was able to get a Tikka T3 for way cheaper as they were phasing them out to go T3X and 260 was all that was left. But I am happy to report it shoots great with both Hornady and Berger ammo.

I had pr 260’s built yrs bak. Chose 260 cause Lapua made brass for it. Now I would choose 6.5CM. You can whore the classifieds here and get lifetime 1x fired brass cheap. Hornady deserves an Oscar for their promoting of 6.5CM. Remington deserves an AssSpankn for just sittn on the 260.
 
IMHO, very much of the 6.5CM's ascendancy is directly related to marketing effort, as opposed to actual performance. IMHO, the actual difference boils down to competent shooters behind competent rifles. If you handload, either can shine for you. If you don't, good commercial ammo is available for either.

With the 6.5CM you get an advantage with neck length, which allows one to seat longer bullets while still retaining a somewhat shorter OAL. I seat to mag length in the 260, and have never seen a disadvantage in the 18 years I've been shooting it.

With the 260, you get a corresponding advantage in case capacity. The 260 lost the race, but to 6.5-284, not the 6.5CM, when case capacity came up favoring it. The 6.5CM's capacity goes the other way, the wrong way.

Additional advantages to the 260, brass availability. That's because, it being based on the 308 cartridge, one can also dragoon .243 and 7-08 into a valid 260 brass supply. Run either one through a 260 f/l resizing die with neck sizer ball, and Voila you have very usable 260 brass. Yes, Lapua is nice; but I only ever paid that premium for 30BR brass. The readily available stuff has done fine for me for nearly two decades, and I haven't bought nominally labelled 260 brass in over a decade; I prefer 7-08, and right now, it's Starline.

BTW, the 7-08 case costs less than the 260.

Accuracy is a tossup. They are both capable of performing above my skill level. After handloading for 18 years, investing in a nearly identical chambering that does the same thing (maybe) just isn't on my list of priorities.

New shooters should choose the 6.5CM because of the factory backing; Rem blew that one.

Between 260 and 6.5CM I prefer the 260 My wife shoots F class with a .260. I have two 6.5 CM's I think the .260 is easier to load for and less finicky. But the 6.5CM is easier in a gas gun. If I were looking for something to hunt with in 6.5, I think I'd go the 6.5 PRC.
And Lord knows I'm going to get flamed for this but I don't think any of them take down anything as well as a .30 caliber. My experience and opinion is all it is though.
 
Knowing my own degree of age and feeble, my choice for hunting would be the 6.5 Grendel. Not quite as crazy as it seems, my selection is based largely on my ability to retrieve my kill.

...Or inability...

I figure 250-300yd is a good distance for that chambering; and honestly, I would never wish to get that close to a Bull Elk. It
is also a fair estimate of how far I could drag a dressed deer on my own. Step, by step...

Prior to the last few seasons, I fielded a 30-06 M70 Featherweight.

I run a run a 260rem in my AT and I love it. Factory ammo is avaliable thru hornady with the 130gr ELD, and it shoot very good. I believe prime will have a 260rem load as well soon.
I bought a box of these as I needed “factory ammo” ? for a range.
