270w vs 6.5 creedmor

I would pick a 7-08 over a .270 every time. The .270 is a great hunting cartridge but it just doesn't have a reputation for long range accuracy plus it isn't really flatter and faster with similar bullet weights than any other cartridge. The 6.5 does have the advantage of long range accuracy with less recoil. Otherwise you're not gaining much over the very accurate and powerful .308. To really gain range and velocity you should look at the 7 MM Mag. I am pretty sure it shoots flatter and has more energy at all ranges plus has a very good reputation for accuracy over any of the cartridges you mentioned.
 
I don't know about Marine corps. but when we qualified with the M-14 in 1967 we shot at man size pop up targets at 600 meters as part of qualifying. The 7.62 NATO was also the round used in the M-60 machine gun.

I guess my old Ruger 77 didn't get the message. My 3 longest shots were with a 270. Two mulies and one whitetail that were around 400 yards, give or take 25. Five shot groups that could be covered with a quarter. The only advantage that I see with a 7mm-08 is the bullet selections. You are pretty limited with the 270.
 
why the 270 barrel will last less than the 6.5? for speed? or the pressure? how many shots can it be?

Pressure, powder volume, speed, overbore ratio... it’s all con for the 270’s barrel life, with no pro’s.

You’re talking 1000-1500 from the .270win before I’d expect to start losing velocity and expect to see accuracy start slipping. 2000-2500 from a 6.5 creed.
 
Wow, you guys are talking some serious range. Perhaps I've underestimated, I was thinking my 18" 7-08 would be a 250 yard max situation. I was staring up the powerline the other day and I saw some movement on the ridgeline probably 350-400 yards about. I wouldnt take the shot because I'm not skilled or experienced enough with my rifle, but the way you guys are talking a 300+ yard shot would be no problem for a .308 or 7-08?
 
The 6.5CM has won the cartridge battle and will continue to win until another cartridge comes along to replace it. The popularity of short actions due to the 308 and the magazines that support them, will always be a big factor.

The 6.5 is going to hold its resale value a bit better than the 270 just because of the rise in popularity.

Depending on the load, and conditions, I mean, know your dope, but my kid's .22-250 is zeroed at 300........ Keep impact velocity in the bullet's design window and don't take bad shots, obviously you'll want to be on a rest. It won't be the cartridge to blame if it's not doable.

Double that for hunting accuracy, and double it again if you limit to 5-shot groups.

...so it'll be my great grand kid's problem.

Like a scoped rifle's mean point blank range (MPBR) to be (+/-) 3".

For the .270 WIN/150 gr. - that's generally:
~ +2.7"@100 yds,
~ 275 yds on the other end,
- w/ ~ a 12" drop (top of back hold) @ 350 yds,
- and a little daylight between for 400 yds.

Freezer-filler.

Pretty sure 3 shot, 5 shot, or 10 shot groups won't matter for barrel life, you're still blowing the same amount of powder down the bore.
 
For our OP's stated purpose, .270 or 6.5CM will function with precious little difference. I liked my Rem 700 .270, but it was light and recoil was more than I could handle with shoulder problems. It killed whitetails very dead and with my reloads it shot dime size groups at 100. I decided on a 6.5CM to try something different and to solve the recoil issue. Not only bought a different caliber, but a very different rifle. I now have a Savage 110 Desert Tactical 6.5CM. With the added weight and soon a muzzle break, the recoil will be insignificant. Already with the weight the recoil is much better. Accuracy is about the same, but I anticipate better long range performance as my loads develop. In either case, I'll never shoot enough to wear out a barrel, since my targets are going to be deer and coyotes. And since I have other rifles I love to shoot too, weariong out barrels is the least of my concerns. So, again, it comes down to the desire to experiment with a different rifle.

300-400 yards isn’t even starting to become an issue for a .308 or a 7MM/08. It might be for the shooter but not the round.
