I see you are in AZ, like me. Of the choices you mentioned, I would go with (in fact I am going with) the 7mm-08. Ruled out the .243 as not versatile enough for my needs (not a varmint hunter), ruled out the 30-30 as too short range and redundant for me (have a .35 Rem), ruled out the 308 as too much recoil in a lightweight rifle (my rifle will do double duty as a youth trainer). That left the .260 and little 7. I am a big fan of both, but the 7mm-08 is just more versatile as far as available loads go, and also for reloading components. Plenty of power for any deer in the U.S., plus you can load it up or down. Also, I figured that in a pinch, with the right heavy load, and very judicious shot placement, at a reasonable range, IF I ever draw an elk tag here, I could use it (although I would probably get a .338 to celebrate getting a tag :grin: ).
Good luck in your decision.
