6.5CM is the easy button/obvious choice for this application. Don't overthink it.
Take the easy win and be happy you have so many choices and available stock.

Very true, but, once you hit a target out to 1200 yards, I find that I want to keep pushing that envelope. I've shot my 223 tikka out to 1028 yards and I'm thursty for more. I want to try King of the mile but I know there is limitations to calibers. I'm hoping that my next build (22CM shooting 95 SMK) will get me to 1400 to maybe 1600 yards but thats just for giggles. Not going to try to hard. I'm also a sucker for anything .22 calibers.
and ELR is defind as what, 3-400 yards for a .22lr is ELR. 1000+yards for 223 is ELR. a mile for 300 Norma is ELR

And by that time he might decide to build something to reach farther but may not and be happy with what he has. Too many newer shooters say "I want to shoot long range and need a 338 Lapua!" and spend thousands and then find out it's a lot of recoil, not really anyplace to shoot it to it's potential and ammo is expensive so they don't shoot and end up selling the rifle. The smart ones do what the OP is doing.
Having shot my 6.5 Creedmoor to a mile with factory ammo and his location with not having a longer range close by he only needs help with his present situation and not what he might do sometime in the future. He can reach out plenty far enough for now with a properly set up 6.5 Creedmoor.
How true that is...some are lucky to have the facilities that allow them to shoot at those ranges. Here in the NE 600yds is the closest I can get to regularly, for me it's prs 22lr and the occasional 600yd plinking session with my old Savage 110LA build that shoots well at that range. If I had more range available I'd do it differently, why overspend and overthink a build I'll never test to it's true potential.
where in NY are you?
Eastern LI...closest real facility is Sheepdog in the Catskills, 3 1/2 hrs away
at least it's a good facility...but yeah that's a drive
if you shoot matches they do back to back centerfire/rimfire. can camp on site too
That's one of those ideas that sounds great in theory and is a mess in practice.
For only 1,200yds. I'd grab the AXSA or AT-X
I hardly use my AXSR for anything inside 1,200yds.

I've been researching various rifle options for myself, looking at long distance hunting and PRS. Given my own personal parameters, I looked up cartridges that were as close as I could find to each other. I've put that info into a ballistics calculator for chart creation. My current choice is to go with a 7mm Rem Mag rifle & round, as it seems to have the best overall ballistics for my parameters. 
4 calibers of rifle round: 7mm Rem Mag, 6.5CM, 300WM and .308 Winchester. Ballistics info from each gathered from Mfr. and range information out to 1800 yards. The OP asked a question...I provided my input. Worthwhile? That is up to the OP.
You can shoot the 7mmRM in PRS matches but plan to have barrels on stand by as you will be running through them.I've been researching various rifle options for myself, looking at long distance hunting and PRS.

If you care about hit percentage, especially first round the magnums are unbeatable. We shoot out to 1200 with 6 dash/br/gt and 6.5 creed but if I was building a dedicated 1k+ gun.....

You get the idea.
1. Trajectory is essentially meaningless for shots at known distances, i.e. target shooting. Wind drift is what's important for hits. Both are improved by velocity, but wind drift is improved much more by using a projectile with higher ballistic coefficient.
2. The trajectories you posted are also just 1 of 100's of projectiles/loads that could've been selected for those cartridges...
----------------------------------------------------
Find the projectiles with the best BC for each caliber. Pick an acceptable wind drift for your purpose at max distance - in this case 1200 yds. Look at the velocity necessary to achieve that wind drift - now figure how much powder would be necessary to get that velocity - and that capacity should start pointing towards a few cases that would work, for each projectile.
Now that you have potential chamberings - weigh the limitations of rifle configuration as well as cost of consumables, heat soak, recoil, and many other tangible and intangible criteria.
