I've been up and down the caliber road myself the past few years; tried several platforms for .30-06, .30-30, and .270; I don't like the recoil of .30-06 (2 bolt action rifles and 1 slide action rifle); I like the practicality and recoil of .30-30 in Marlin lever guns...but I wanted some more snot for my primary hunting rifle; tried .270 in a slide action which turned out to be a troublesome plaform...liked the recoil and accuracy enough to get a bolt action; liked the combo of .270 and Winchester M70 Black Shadow that I have had a thumbhole stock fitted and a very good quality Sightron scope mounted...
back to the caliber...lighter loads good for larger varmints (coyotes, foxes, other scroungers); medium loads good for whitetail deer and smaller bears; heavy loads, expecially those that are bonded, partitioned, or solid copper, are good for larger deer, bear, and even elk; the recoil with factory 150's is very managable...not nearly as bad as .30-06...not nearly as light as .243;
as a compromise between the 'brushbuster' .30-30 round nose and the higher velocity of the .270, I found Federal Power-Shok 150 gr round nose (similar profile to a 150 gr .30-30 round nose, but with more snot); I hope to make this my deer/bear load for this year while I save the brass and reload a good ballistic tip load for next year
