First, will you be reloading or shooting factory ammo? There is more factory ammo variety available in .243. Incidentally, .243 (6mm) is the minimum bullet size allowed for big game in Colorado.

If you are reloading, and considering the Tikka T3 Lite, then I would suggest you consider the 26-06. The T3 only comes in long action so you might as well take advantage of it. And, the 25-06 will have somewhat lower recoil than 7mm-08, which is important in a lightweight rifle, but has more punch than the .243. In fact, recoil might suggest the .243 in any case.

For elk, .243 is adequate with correct bullet, distance and shot selection. More on this if anyone is interested.
