While I wouldn't say that a 270 trounces a 7-08, I will say the 270 I have and the 7-08 I had, both with 22" pipes, the 270 could obtain higher velocities with less heartburn. I doubt any animal could tell the difference.

All things being equal I doubt there would be any difference, because the 7-08 would have to be on a standard length action as well, the only favor I see in the 7-08 is slightly less recoil.
 
7-08 with 20" pipe will do 2975 fps with 120's. 270 with 24" pipe will do 3100 fps with a 130gr, which has a higher Ballistic Coeffecient. 270 will out perform 7-08 at all distances
 
I've reloaded for 1 rifle of each, both Rem 700s.

The 270 was 'average' in that it took a usual amount of load development to get a good one, but a good one it was.

With the 7-08, I literally could do no wrong. EVERY bullet and powder combination shot into less than 3/4", every time.

For whatever that's worth.

Accuracy, not terminal ballistics, has nothing to with the cartridge.

If that's true, then why do benchresters and other target shooters prefer some cases over others? There are many cartridges out there that are "known" to be generally more accurate. The .222, 6PPC, .308 come to mind right off the bat.

It has everything to do with the quality and consistency of the components, the consistency of the assembly, the quality of the barrel and chamber. Most importantly it is how all the above fit together in the package your shooting.

That's why I added the phrase "everything else being equal" in the OP. Same type bullets, same bbl, same gunsmith, same (almost) action, etc.

What makes you think a 270, or any other cartridge running comparable equipment can't be as accurate as any other?

I do think the 270 can be scary accurate, but was looking to see if the 7/08 was more or less. I've only loaded for a couple 270s over the yrs and have never even fired a 7/08.

What exactly is the outperform criteria....

I believe the thread was about accuracy, which was pretty well decided to be dependant on the rifle more so than cartridge, ...
or at least the combination of the two, but certainly not dependant on the cartridge alone...

When we talk outperform, or at least when I do,..two of the last calibres that I would compare and assign one as trouncing and outperforming the other, would be these two.

In addition what is outperformance exactly...

Is it a bang flop...everytime... is it accuracy? Is it the average hunters ability with a given calibre? Is the elite marksmans ability with a given calibre?
Is it FPS, ftlbs, or some combination....
 
Here is another way to look at it.

With the 7mm-08 you have a shorter action and a slightly bigger bore, so if you take those weight savings and put it into a slightly larger barrel diameter to bring both firearms to the same weight you should have a stiffer barrel on the 7mm-08 which should translate into greater accuracy potential, all things being equal.
 
I don't think the cartridges will have anything to do with it. All things being equal, by placing the barreled action in a vice and firing I'll bet they will both print the same, given the most accurate load for that particular barrel. Everyone will tell you the .308 case is inherently accurate. I hate that term. I don't believe there is such a thing, and it's simply a phrase coined by the Col. Craig types. Any cartridge has the ability to be accurate when given the proper platform. I don't care how many competitions are won with a given case or another either. And I also don't care about longer actions flexing more then the stiffer shorter actions, that's just nit pickers being stupid. The fact is I don't care how good a shooter is, nobody ever will be able to use the worlds most accurate rifle to it's true potential. I can hear the naysayers now preaching about mile and a half shots by military snipers. Yippidy doo. I've seen them shoot, and their human. They make mistakes too. Both cartridges are excellent and great accuracy can be had from either. And shooting from a field position, not a single person could tell the difference between the two. Both recoil the same, both shoot so similar it's ridiculous to argue about it. The only thing I could say is the .270 will fire 130 and 150 grain bullets, where the 7mm-08 will fire 140 and 160 grain bullets. I know there's 140 .277's and 150 .284's, but the previous weights are what make the cartridges. A 130 grain .270 bullet will do exactly the same thing as a 140 grain 7mm bullet. Once the proper load is found for each, I don't think anybody could shoot well enough on their own to determine which is most accurate.
 
The gun shoots the projectile to one point. It is entirely up to the operator to find this point and use it to its full advantage, Every barrel and gun shoots different but truly the shooter is the accuracy in the combination. I have seen 4-5 thousand dollar guns shoot terrible compared to a 4 hundred dollar bought used off the EE. Big money does not assure accuracy...patience,practice, rifle- ammo combination and knowledge of the guns capabilities provides true accuracy.

An instance is that a young fellow at a competition on Sat. placed in the top 3 ...first time in competition in his life...with a $500 dollar .223 that he bought on EE. Handloads and a $100 Tasco scope completed the outfit. He was shooting against experienced shooters and some expensive equipment or w.h.y.. his .223 was a single shot and it was a timed event.
 
as much as I'd like to spend the morning reading and discussing about what is more accurate, I will go load some ammo and actually go shoot some rifles today :)
 
.270 Win vs 7mm-08....

Got rifles in both.

Have had great accuracy from both.

Would be hard one for me to choose between.

NAA.

Different bullets, different weights, etc etc etc:rolleyes:

Do think that being different calibres might also make a difference? ;) :D

Still, the top 3 in each bullet weight goes to the 270. Could a pattern be emerging?



I do however like the 7mm-08, even though I don't have one ...... yet.
 
I was just going by what the Remington site said under ballistics...I compared awhile back a 140gr .270 and a .140gr 7mm-08...according to the Remington site the 7mm-08 was faster and had more energy at 400 and 500 yards...check for yourself
But of course different loads and different bullets will not perform exactly the same....I like the 7mm-08 more because its a short action and there is a much better selection of 7mm bullets out there...
