If I were choosing between a .308 and a 6.5 Creedmoor in the same platform, is there any reason to go with the .308? With modern bullet design, does the advantage of more bullet mass do enough at closer ranges in terms of terminal ballistics to outweigh the well known external ballistics advantages of 6.5?

I bought a Ruger Precision Rifle in .308 because I thought it would be more interesting at shorter ranges. Turns out it's just more shitty at all ranges. My buddy picked up the 6.5, and it's so much better. The biggest benefit to me was lower recoil. The RPR is bolt-automatic, so there's nothing to dampen recoil except the rubber butt pad on your shoulder. The .308 is a proper kick the the shoulder. 6.5CM lets you know there's recoil, but it's really not that bad.

6.5CM ammo has come down in price quite a bit, the bullet selection is good, and it fits in .308 length receivers. My next project (if I ever get back into gun projects) was to build an AR-10 in 6.5CM.

Shaking it up and speaking from a fudd hunter/cheapass perspective, .308 win is still my personal preferred short action caliber for two major reasons beyond my built up infrastructure for the caliber that I don't even own anymore. I can load a little bit heavier projectile for that slight edge on penetration and loaded ammo and quality components are more numerous, particularly now with most people understandably flocking to 6.5 creedmoor.

I can weight sort lake city brass, and often source pulled or surplus quality .30 caliber projectiles ie nosler partition cosmetic seconds, federal fusion etc. .264 is definitely scarcer. If I want to get really fancy, Lapua brass is much easier to come by for it from secondhand sources whether once fired or unused sitting in the garage.

I can walk into Powder River Taxidermy in Broadus, MT aka nowhere and buy an overpriced box of shit ass 150 grain .308 win core lokts in a pinch, probably not so much for the 6.5 yet.
I never thought that was a real problem until I was stationed in New York and had to find even .280 Remington for my hipster .280 Ackley Improved since all my ammo got left at home.

From a logical/ballistics standpoint I absolutely agree that 6.5 creedmoor is a more efficient, better overall cartridge though.

Absolutely! 6.5CM is superior ballistically overall, but .308 Win has better logistics.

In this coof environment, 6.5 creed has actually been easier to find for me.

.308 due to logistics. Also if you tire of the (308) rifle you have, you can ditch it and be more likely to get a different one in the same caliber and not need to ditch your ammo too. You can just transition easier.

Logistics, as others have said. Just easier to get and still kills shit dead. I'm albe to find steel case easily at academy.

Personally I went with the .308 and now kind of regret it. :|

I was thinking of this topic this evening and another thing occurred to me that may be relevant.

30-06 rifles are still a thing. The longer action made them inferior to .308 in terms of weight and accuracy but they carried on because of the potential for the punch from that little extra bit of powder in the longer case.

Is that the same sort of thing we're looking at with 6.5 vs 308? Will .308 continue for 50 more years because it may be more useful than the ballistically superior 6.5 inside certain ranges because it can deliver more bullet weight on-target? What will 30-06 look like by then? Or will it and 300 Win-Mag have both been supplanted by 300 PRC because the action length and accuracy and weight issue will have been solved by then?

Cartridge progression is a weird and wild thing considering game animals haven't changed for millenia.

Years ago I'd have agreed, but I just ordered an MDRX in 6.5. The only logistical shortfall I shortfall I see for 6.5 right now is if you wanted a semi auto, you'll probably have to order one, but same could be said for 308 right now.

I debated the same all year before ordering. Ammo wise there is plenty of 308 and 6.5 in my area. Picked up a 200 rd box last week.
