I would just assume they are all completely off. Id rather not turn this into a 270 vs 30-06 thread. If comparing 150gr. vs 150gr. its a no brainer for me.

Okay, then how's this:
I think it's a misconception to think that the .270 is better than, or even as good as, the 30-06.

I'll be taking my 270 hunting for the first time on October 17th. I had it at the range trying a bunch of different premium hunting bullets and I found that they all grouped similarly well with my Savage. I had planned to choose which I was going to use based on its accuracy in my rifle but since they're all roughly equal, I don't know how to choose.
I will be hunting Mule Deer, White Tail Deer, and Elk.
Which should I choose:
130gr Nosler Partition
130gr Trophy Bonded Tip
140gr Accubond
Right now, I'm thinking the bonded tip. In theory, the bonded front core and solid copper rear section should hold together better than a non-bonded partition in an Elk.
Of those three options, what would you all use for this hunt?
By the way, before moving to Alberta from Ontario, I used a 300 Savage and found it satisfactory. In Alberta, I've used the 30'06 and found it satisfactory. I'm sure the 270 will be great too, especially since my father used the 256 Newton for decades to do the same job at aprx the same velocity but without the benefit of the above premium bullets.

I looked up the number in that chart you're all talking about from Federal Premium which is the source cited. They are 100% accurate. Note that the chart is talking about energy delivered to game in Ft/lbs, NOT speed in fps.
It seems that at 150gr each, the 270 beats the snot outta the 30'06 at 150 yards and out.

The 140 ABs work great, but really, I'd be asking my Dad to borrow his 256.
That...wouldn't be necessary but I save it for rather special occasions.
You can read about this particular firearm and its history here:

Also, why the ABs over the partitions or the Trophy Bonded Tip?
First off, my condolences.
Second, the partitions work fine, I have used them, the TBs I have not used so I try my best to avoid the armchair advice but I bet they will work fine too.
My BIL uses the 140 AB in his 270 and has had very good results which is why I singled that one out.
Still I have to say I'd be packing that 256. Or get a stock made for the 30 Newton so the original one stays in one piece. That in my mind is the best 30 magnum ever made...... but this is the wrong thread for that so I'll just shut up.

There we go... now we can have both. A 30-06 vs .270 thread, AND a thread about .270 misconceptions.
So, the .270 with todays modern bullets equals the 30-06 of yester-year? So the 30-06 with modern bullets must equal the .338 of yester-year.
The 30-06 still wins.
Oh... by the way, before anyone gets too upset, I'm just being a smart-@$$
270 Win is excellent because it optimizes the "M1 Garand" rule for big game hunting:
an average hunter can only handle the recoil equivalent to M1 Garand (9.5lbs rifle, 150gr 2800fps).
The 270 can drive high sectional density (and ballistic coefficient) bullets while staying below the maximum reasonable recoil level.
Nothing more, nothing less.
Therefor any potent 270/7mm cartridge is an excellent big game cartridge, 270 Win got there first in 1925 and got great publicity.

The 150 grain bullet weight IS NOT the optimum weight in a .308 bore. In my experience the 165 grain is the best choice ballistically for a .308 bore. Even in factory loads the 150 grain in a .30/06 starts out faster than a 165 and at 300 yards is moving slower than than the 165 grain load. So, not really a fair comparison as a 150 in a .30/06 is less than ideal. Besides muzzle energy itself is unfairly slanted towards higher velocity rounds and is not the only yardstick for killing power.
To illustrate a .243 Win. with a 90 grain boattail at a muzzle velocity of 3300fps has a muzzle energy of 2177 ft.lbs.
A .45/70 with a 405 grain flat point at a muzzle velocity of 1330 fps has a muzzle energy of 1590ft.lbs.
I know which one I would rather have in my hands to shoot a moose or bear.
The formula E=m times velocity squared is not the be all, end all, apologies to Albert Einstein.

Do you still have access to the 256 ? Ill be using its kissing cousin the 6.5-06 this fall for Deer...of course Ill have a 270 with me but Ill probably loan it to my Dad since its very light to carry. I push 130's at about the same speed with both...I always seem to go back to the 6.5's for some reason.
[talking out my arse]
But that's the point: at recoil levels that are amenable to lots of practice, the .270 outperforms the .30-06, giving the same SD and BC as .300 win mag without the pain and muzzle blast. It seems that it's not likely that game notice much of a difference being shot with either, so why not go with the 150 grain .270?
This is an argument that leads us down to the .260 Remington and 6.5x55 on the lighter side and the 180 grain .30-06 and .300 Win Mag at the heavy book-end to get the same kinds of ballistics. If you wouldn't shoot 180 grain .30-06 in lots of practice, the .270 fills the bill better. Many would argue that the 7x57 Mauser is an even better balance. When you consider 'bang for the buck' - buck being recoil - the .270 might be an ideal bullet weight in an ideal weight gun with acceptable recoil. A .30-06 with 180s in the same gun might be a bit brisk, and a 7x57 in the same gun might be a bit slow.
The 150 grain .270 might be the perfect balance of ballistics, punch and recoil in a portable rifle that could take any sized game.
[/talking out my arse]
Of course this is all the culmination of a lot of what other people wrote of their decades of experience. I intend to find out if all this bears up to their claims, as I now have one of each.
When I sold my .270 a couple decades ago I immediately regretted it. The rifle was accurate and didn't hardly kick. But I had bought a lightweight .308 to replace it and had a deal in progress. I think I didn't understand the .270 then, because I never would have switched knowing what I know now.
If you guys keep this up you are going to prevent me from pulling the barrel from my '49 Model 70 in 270......I was going to build something with it but maybe I should leave it as is...but then a 9lb 270 is not something I would likely carry around either...
A Vanguard in 270 was my second big game rifle. Bought it new in 1990, took maybe a dozen deer with it over the next 10 years and then decided I didn't need it....might have to carry one of the 270's this year.....

I agree, 100%. The .270 is a fine round and unless you are hunting really large game exclusively, I would prefer it over the .30/06. Personally I hunt with a Husky in 7x57 and 140 grain bullets and have not found it wanting.

The .270 is not a myth, it's a legend. I'm a .270Win fan and latter in life convert, but my heart lies with the 7mm bullet. If the .280 Rem came first, the saga may have been a little different. But it didn't , .........so as for the optimum bullet diameter in a case the size of an '06, being .284", firing bullets ideally 145-16o, theres nothing the .270 really hadn't already done,...so down went an excellent cartridge the .280, nearly as obsolete as the .284Win which i own and like. All because of that darn .270.
The legend lives!
