I just ran the numbers just for sake of interest.
I used max velocity's in the Hodgdon website and used the highest BC eldx bullet that these guns generally will stabilize to try and keep it consistent. and the range they still carry the 1000ftlb of energy to (just for comparison as i know they will kill under 1000 still easy provided your bullet can expand at that distance) and a 5mph 90deg crosswind
Note: i used 140gr data for 270 as they dont have 145gr data
260- 143 ELDX - 2796FPS- 1000Ftlb = 740 Yards @ 1775fps Supersonic (1350fps) until 1110 yards - 17.25MOA drop @ 735 yards - 1.75MOA wind
6.5CM - 143 ELDX - 2795FPS - 1000Ftlb = 735 Yards @ 1780fps Supersonic (1350fps) until 1110 yards - 17.25MOA drop @ 735 yards - 1.75MOA wind
270 - 145 ELDX - 3023FPS - - 1000Ftlb = 850Yards @ 1768fps Supersonic (1350fps) until 1200 yards - 18.75 MOA drop @ 850 yards - 2.0MOA wind
7mm08 - 162 ELDX - 2725FPS - 1000Ftlb = 840Yards @ 1675fps Supersonic (1350fps) until 1150 yards - 22.25 MOA drop @ 840 yards - 2.0MOA wind
You can probably get more distance out of all of these with different bullets like the LRAB etc but this is just to have a reasonable comparison out of factory available rifles.
Atmospherics used was just whatever it is today in Hamilton
I own a 6.5CM, 243, 308 , 300 win mag but almost always reach for the 308 as it does everything i need for general sub 500 yards shooting but i grab the 300 win mag if i know long shots are likely.
