Exactly, that's my point. A 270 will have almost the same trajectory out to 500 yards as the 7mm but with 250 ft-lbs less energy.
.270 vs. 7mm Rem Mag vs. longer range calibers?

I’ve killed a bunch of game with it. From 20 yards to 450. Do you have some experience with it?

I was comparing a 270 with 140 gr bullets at 3000 fps with a 7mm with 160 gr bullet at 3000 fps. Off course the 7 mm will be flatter shooting with a lighter bullet at 500 yards, but the same could be said for a 270 with 110 gr ttsx at 3400 fps. I'm not debating the energy between the two, the 7mm clearly wins that.
In what way does it not win?
I have used a specific sighting for hunting since the early 1960's +3" at 100 yards
This usually gives a point blank of well over 350 yards with the likes of the 270 &
7mm Rem Mag. The trajectory from actual shooting looks like this: 100 - +3";
200 - +3.25"; 300 - -1.5"; 400 - -10.5"; 500 - 26" [160 Accubond at 3050]
For an Elk or Moose, you can hold on hair out close to 500, well beyond many
shooter's capability.
FWIW, My 308 Norma Mag with the 180 AB at 3100, and my 8mm Rem Mag with
the 200 AB at 3200 have almost identical trajectories. Dave.

The 270's trajectory is almost as flat as the 7mm in the two loads I mentioned above, that's all. It wasn't about winning, just comparing the 270 to the 7mm. Where it does have an advantage is in a lighter weight rifle and less recoil. Are there any other cartridges out there that will shoot flatter than a 270 with the same amount of powder and still be capable of taking elk and moose. If there is, there's not many.
Just to comment on the last sentence. Many have compared, and honestly believe that the 6.5 Creedmoor is equal to the 270 Winchester, which is absurd. One caliber cannot be compared to another. There is absolutely no other cartridge that compares to the 270 Win., no other ballistic twin. There is also no comparison between the 270 and 7mm Rem. Mag..........NONE!!! It's hogwash to even debate these two cartridges of any sort............just a lot of talk for nothing.

My favorite 30 cal magnum
and 
not meaning to hijack this thread. My 1st was a Parker Hale that I put to use in an area, probably not too far from where you're located. Wells and Bowron Lake area. Have since replaced that 308NM with one in a model 65DL Schultz & Larsen. My best accuracy has been with a 200gr Sierra SBT and a top end load of IMR 4350.I don't have a 7mm RM but do have a virtual twin, a 7x61 S&H Super. This and my 270,
with close by bullet weights do appear to have similar trajectories. I'll have to see if I can find similar trajectory results, with my 308NM and 358NM.To also consider them vastly contrasting is also complete hogwash.

There are cartridges that have similar trajectories with certain loads and that is what i was referring to, nothing else. The 270 win with 140 gr bullet has a similar trajectory to the 7mm rem with 160 gr bullet when both are started at 3000 fps.
Every cartridge has their own fingerprint, NONE of them are the same. Your beloved 6.5 Creedmoor has close DNA to the 260 Rem. and 6.5x55, however, you find it superior then the latter two. You favor one with superiority with almost equal ties, and yet you find close similarities from two different caliber and cartridges.
Yea, that’s it.
Nice Shooting Cartridge - Rifle there Chuck - are you gonna change your Signature line now that the 30-06 has being BESTED !

Thanks for the information. But you have missed much. I’m too busy to get into this at the moment, but you are making this far too convoluted.
