There is no "best" but my favorites for antelope are my .257 Roberts and 6.5-06AI. It doesn't take much to put one on the ground, especially the does I normally hunt.
Might take the #1 .280 this year, though - its a virgin in my hands and shoots great.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
I'm taking my 6.5-284 in two weeks to NM for Pronghorns. Killed one last year with it. This year, its wearing a Z5 Swaro with ballistic turret calibrated to the load. On a bench, this gun will shoot 4 1/2" at 600 yds. with progressively smaller groups back to a hundred where it shoots teens and twos. Now, with a bipod and me shooting it, probably not that good. Should do the trick with 140 SST's at 2,950 fps.
My latest project is a .240 Wby, a 26" HS Precision SPL and a Conquest 3-9x40. It could become my Pronghorn/Whitetail rifle. It's lighter and while not quite as accurate, still sub MOA with the right loads. I think the 6.5 would be better beyond 450 yds, or so, but how often does one need those extreme ranges to kill a speed goat?
Should I just use a 270 win. with 130 gr. bullets or my 300 win mag with fast, light 110gr TSX bullets?
Shooting will be max. 400-450yards.
Don't overlook a 270 with 150's. They'll shoot to almost the same point of impact and will have more downrange energy at long range. They'll also buck the wind slightly better. I've killed lots of deer and elk with those.

It's not over when you lose. It's over when you quit.
270 is a good all around choice for the three you mentioned. Then again my buddies from my hometown all shoot 300's with 180 grain pills for coues and antelope and that does wonders. But for 450 yards max like you mentioned,I don't see the need for more than a 270. Hell a 243 would be hard to beat too. Its when you get out passed about 500 yards that I would look to a mag with a good bullet. I shoot a 7RM.

"..faith is being sure of what you hope for and certain of what you do not see.." Hebrews 11:1
For Coues I carried a .300 Win Mag for years loaded with 150, 168 or 180 grain bullets, but am now using a .270 w/ 130s. Both work fine, my vote would be the one you shoot best. Mike
Surprised no one mentioned the 25/06 with a 115-grainer. While you can't go wrong with pot full of cartridges that have roughly the same trajectory, the 270, being among the best, I always thought the 25 was made for the little goats and deer.
