One of my favorites, is the 9.3X62 also have used the 6.5X55 and 6.5X57. All work well. At higher velocities the smaller rounds cause more meat damage. More explosive hits. With the 9.3X62 I do not have too much recoil, and it has proven to stop most game in it's tracks with little to no meat damage. At least for Whitetails and Mule Deer. Have also used the 8mm Mauser and 30-06. It really depends on the bullet, velocity, and the game one is trying to take. For myself I have found for the most part in woods hunting where long range is not an issue bigger is indeed better.
