I like the .270. But then again it is just a necked down 30.06. It shoots a bit flatter and kicks a bit less, which is the main reason that I shoot it. I would almost bet that if you where to take a poll of all of the members here that the 30.06 would be the #1 used rifle with either the .270 or .243 coming in 2nd. Idunno, there are so many popular hunting calibers nowdays. I am sure that the 30-30 would be right up there, with .308, 7mm mag, and the .280 all possibly vying for the 2nd spot as well. Behind an overwhelming 1st being the 30.06. I might be wrong, but the 30.06 is more than likely the king.
