Guess I'll go with the 30-06. Only other 30cal I own is a 30-30. I don't use either very often. Our small bodied deer don't require that big of a bullet.
Of the more popular 30cal rounds, I just never have been a big fan of the 308Win and the 300WinMag is way more than needed for anything I hunt. I've owned a couple of 300WinMags and still have brass and dies but the more I shoot my smaller caliber rifles, the less likely it is that I'll ever own another one.
