I like the .270..... well, because it works, and quite well as a matter of fact. My Grandfather always used it (Remington 721, since 1949 when he bought it), I bought one (a Howa 1500 / Mossberg), in 1991, after reading Jack O'Connor's praise of the caliber. I found it perfect for taking out woodchucks and deer. I have 3 .270's now (Remington 721, 700 BDL and Remington 7600), and find them just as deadly on deer as a .30-06, it just doesn't rip your cheek bone or shoulder when you touch her off. My buddy has a .270 Ruger 77 and would never part with it. I talked him into the .270 caliber after he developed a flinching issue with his .30-06. He would never go back, after getting used to the .270 and seeing how quick it dropped his first deer.
Sure, a .25-06 or .257 Roberts, or 7MM would work just as well, but it all boils down to shot placement anyhow, be it squirrels or Moose. Do your research and shoot what you like. You may end up swapping a number of times until you find what suits you. My son in law loves the .30-06 caliber and doesn't mind the recoil. It works for him. To each their own.
