Wapiti, from what I've read the .260 Remington has a larger case capacity than the Creedmoor, but the Creedmoor has a longer neck so you can seat those long 6.5's deeper to fit in the magazine, but not encroach on powder charges. Pretty much equals in the field. I've narrowed down my search for a new rifle in either of these calibers.

It's a heavy brute but it is solid on a bipod and coyotes don't stand a chance.
That's a good point if you do not reload, getting ammo is as important as anything as we've all learned.

Yeah, there are some really good factory loads for the 270, and even the standard "cheap" loads from the big companies are really effective on deer. At real long range in heavy wind (which being from KS you know all about) the higher BC bullets start to really take over.
I find running the ballistics program and shooting in real life that I'm better off deciding how far I want to be able to shoot and weighing that against how fast I need to be able to shoot. Until you get to extreme range the short time of flight a high velocity gives you often beats the efficiency of a slower, higher BC bullet.
For example for coyotes I use a 70gr ballistic tip from a 6mm at 3824fps with the Hodgdon Superformance powder. It lets me hold dead center out to 350yds and stay within the vitals, no guessing at hold-over, no dialing, just shoot. Past that the low BC has the velocity dropping off, wind drift increasing, and it's easier to make hits with some of my other rifles. Coyotes often feel safe enough to stop and look back for a second somewhere in the 250-350yd range where other hunters might pass on a shot. If I'm ready to shoot the instant they stop to look back I get a lot of dogs others don't. For an antelope or deer hunt I'm hopefully shooting prone or from a bipod at a animal with no idea I'm there, plenty of time to range it and use the wind meter and wind chart, dial the 264 correctly and send a 140gr Berger right where I want it. I can shoot farther with greater precision, but it takes more time to set-up properly for the shot.
Hopefully some of this will help the OP, really think about what you want the rifle to excel at and plan it accordingly.
pick one go kill stuff
Or buy all 4 and kill lots of stuff.

The 243 will kill elk, but you'd better hit them in the right spot, or you're in for a long track job (as with any poor hit on an elk). The .270, I believe, also shoots flatter, so there's not as much drop at distance. I'd just go with the .270 - especially if you want to hunt animals bigger than deer or antelope with it in the future.
This said, I don't have a .270 (but I want one REALLY bad). I do have a Win. .243 feather weight, and it shoots like a dream. My other favorite for deer/antelope is a Sako .25-06. IMO, that caliber is about as good as it gets for anything deer size and down.

I've shot whitetails with my 243 with a 100grain barnes x bullet and it knocked them down. They are a tough customer but it is all about placement. I wouldn't shoot more than a couple of hundred yards at anything deer sized with the 243. I do most of my hunting with a 7mm mag with a 140 grain barnes triple shock and it is awesome.
As a former big game guide in Wy I really am partial to the .243. Just about everyone in my family has taken deer and antelope with the .243 with about 98% going down in their tracks no second shot needed. Some of us even use it for Elk although you have to know your gun and its limitations Sierra 100 grain bullet at about 3000 feet per second. Wife has needed a second shot once in 40 years on antelope and deer.
My Tikka t3 featherlite in 270 win is my main hunting rifle, whitetail, mule deer, elk, and black bear. It's accurate, not terrible recoil and inexpensive to shoot. I would think the 270win is a more versatile caliber than the 243.
