6.5 CM it a much better cartridge for a short action rifle then a 260Rem or a 6.5 Swede ! PERIOD ! RJ

Never owned a swede on a short action. Did anyone build one? Only advantage of the cm is you dont have to push heavier bullets further in the case. As I stated, Rem has started putting faster twists in their rifle, so that point is moot. Seriously, I've used both, still have a 260. And had a 6.5 Panther before that. But that was a Win 70, so no short action issues. - dan
 
I'm with Buckmastr and cockawee1. Which one is "better" is true only at very marginal areas of their use.

One will do the job of the other under the vast majority of conditions/uses.

I prefer the 6.5 CM loaded from light 100 gr loads up to hot 140 gr loads and feel it can do anything the 308 Win can do, but I've never felt bad about hunting with a 308 Win either, and would happily continue taking game with both of them. They've been great thus far.

I don't even shoot the manbun, I shoot even less hp, 6.5 Grendel...the manbun is too manly for me. ;)

And bruh...there's a crapload of people out there that don't reload, rebarrel, and have their own smith lol. There is a huge difference between them, one was designed around light bullets, slow twists, short necks...a 20th century formula, the other takes all that we learned since and applied it to the 21st understanding of not just ballistics in the air and terminally but the rifles, magazines etc. also. Solved all the problems of the 260 and makes it all off the shelf. Why hate that? It's called doing it right the first time. Who doesn't like that formula? You don't think we didn't learn a few things over 50 or so years? Well we did, and pretty bright dude put it into a next gen short action cartridge, we should saying thank you lol.

Yeah.

When it comes to 260 Rem vs 6.5 CM for me its pretty simple...as you said, factory availability is better. In rifles and in ammo

Then again I DO reload, and the powders recommended in the manuals for 6.5 CM are ones I like better and have more of than those for 260 Rem. So for me its win/win. Makes trading a couple percent more fps kinda not worth the squeeze for me.

BTW Blakey you've *almost* got me talked into a Grendel hahaha. If I didn't have a CM already I'd probably do it. Probably. 300 BLK or 7.62x39 is filling that slot for me right now. I see why it fills your needs though. Would rather shoot a moose with the Grendel lol.

Was thinking of a Grendal, but the newer Arc is more interesting to me. I see Brownells is already selling barreled actions in this, the Mossberg mini. - dan

Oh that sounds cool! The Arc looks way efficient. Find that an interesting one too.

If you make the jump into it, looking forward to seeing how it goes.
 
Cockawee1,

If it has not been pointed out yet (I haven't read all 13 pages) this might be something to consider.

I hunt with monometal bullets. They really don't lose a lot of weight.

If one compares a 120gr or 130gr monometal 6.5mm bullet that doesn't really lose any weight to a 165 or even 180 grain 308 cal bullet that loses 30% of its mass...you're looking at a .308 cal bullet weighing between 126 and 115 grains.

Not that big a difference, and I think most people would consider 70% weight retention to be pretty good for a big game bullet.

Likewise, in the 308 you can load a Barnes 130gr TTSX to about 3000 fps and have basically the same ballistics, terminal effects and low recoil of a 6.5 Creedmoor out to 300 meters. And again, your retained bullet weight will be pretty much spot on with a 180 grain that loses 70-75% of its mass after impact anyway.

I like both a lot. As a hunting cartridge typically used at short range, they hit big game hard. People say you have to drive them fast and they kill worse when they are slow. Maybe. Can't say I have killed farther than 130 meters and it did a real number every time.
 
No. After hunting with both I really don't see a need to.

The *only* possible exception might be if someone was dead set on needing more oomph behind a 200gr Partition etc around big bears. That ain't me.

Inside 300 yards no deer, moose or bear will feel the difference in terms of hunting. Unless you REALLY want to break down bigger game, I don't see the point. Cartridges are all a lot more alike than they are different, in general.

My 2 bits.
 
I often wonder what I could re barrel my 6.5CM to when I get a new one. Look at data all around and usually come up with the notion that it will probably be another 6.5CM. When I bought it I though that I might not like it so I could just make it a 308, however that’s not the case. Things it can do: big enough for all game, small enough for paper and steel punching, small enough for coyote’s, low enough recoil for PRS, decent barrel life, factory ammo and components everywhere, everyone from young to old can shoot it, and also does well out to 1000 yards+ on paper and steel. I have yet to see a post bragging about it outright, or someone at the range talking it up like it’s the new sliced bread, however maybe more people should be. I still wish I also had a short barreled 308 to mess with.

My ratio of people complaining about "the overhyped 6.5 Creedmoor" to hearing people actually overhype it is about 100:1
