All 3, including the 30-06 are in my safe at the moment. I don't hear any fighting going on in there! You can replace them all with a 7-08.

Have you .270 guys read Craig Boddington's article on the .270 Winchester that is in the current issue of American Rifleman, May 2016? Be careful you may wet your pants.  Haha.....loved the article.  Don't quite agree about the 7 RM not being a step up though. It sort of takes over in bullet weight, trajectory,and ballistic goodies where the 270 leaves off. I love it, too. I also love how the 270 causes so much heartburn on here....LOL!

I'm not sure which is more worthless, Craig Bottington, American Rifleman, or the 280.
Best part of a 270 is the eye rolls it gets here. There are plenty of places where its more 7 Mag'ish. But the difference between a high BC .277 and .284 is about a 1-1/2 mph wind call at 500.
And there ain't a person here capable of that.

Those who must raise their voice to get their point across are generally not intelligent enough to do so in any other way.

Whatever the question was, the 30-06 is the answer!

I get the loony thing, but if ever two cartridges had about fugg all difference between them, it's those two.

For a bit of fun the other day I got all my rifles out of the two safes and started looking at them and realized how damn crazy this rifle loonieism really is. I have so many rifles that do the same darn thing it's crazy. Sure has been fun gettin em all. I could easily get by with two to three and be just fine. That's really what this is all about,right guys? Best to all......goodshot!

That never even entered my mind before I found the fire. Put a fast twist on it to cause even more hand wringing  I do like both the 270 and 280 but I ended up with the 270 Win and am happy. Still may get a 7x64 or 280 as well one day though.......

I'll throw one more thing into the fire. Have a look at the Nosler laoding website and look at the case capacities of the 270 and 280 AI. About 1 grain.......
Which still makes me wonder how/why we see the 280 AI vels that get posted on here and on Noslers own website.
I love the 280 - had one since 1982. That gun was magic to me. I still fight not buying a 280 AI in a Montana even though I have a 270 that gets 2900+ with 150 Partitions......

When it comes to the cartridge....Um.... I don't care!
My question is/was/still is.
What was the point of a bullet that is .007" smaller in dia.?
When there were so many .284 options, what did .277 do?

Read Boddington's recent article in AR for a partial explanation of why .277 instead of .284.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

A bit more capacity for the 280AI,and loading to 65,000 psi . Plus 26" barrel IIRC, don't have the manual in front of me...... Little things add up.

The 1-2 gr extra case capacity, 2" of barrel, and 0.007" bore size aren't going to equal 200 ft/sec. Both have SAAMI of 65k psi.
Example:
280 AI (26" brl) 160 gr 3 loads ~ 3040 ft/sec
270 Win (24" brl), 160 gr, 2825 ft/sec
280 AI, 150 gr, 2 loads at or pushing 3100
270, 150 gr, 3 loads at or slightly above 2900
Hodgdon tells a completely different story.

When there were so many .284 options, what did .277 do? Are you aware of diameter weight BC correlation? 7mm has 162 AMax. Pretty much a wash below that. And if you think you can see the difference anywhere other than a chart, you're FOS.

Well Bill...I think we agree. If the capacities aren't that different,then it can only be one thing.....pressure. It sure isn't magic The 280AI does have more capacity than a 270....that's what they call it "improved". So I would expect it to be faster. A 160 .277 is not exactly the same as a 160 7mm. The 7mm has more base area for the gas to push on (Waters and JOC had that conversation 50 years ago A better comparison is the 150-.277 vs the 160-7mm Velocities don't just "show up". There's always a reason...whether different barrels, lots of powders, bullets, primers, throats.Capacity..... Million reasons. Besides you can't tell all that much about cartridges so closely matched by reading about it....they are too close. You have to take a bunch of rifles and shoot them with a bunch of loads and see what they do. You'll drive yourself crazy reading those numbers. End of the day: 270 Win with 150....2900-2950 from 22" barrel. BTDT. Had one that did 3000+ with a 24". Where's that leave the 280AI? Don't know and don't care. I shoot 7mm's with belts cause like to push 7mm bullets fast.

160 .277 vs 160 .284 might not be the place to look. But, 140 .277 NAB's @ 3K vs 160 NAB's @ 3K is pretty interesting.
