I've carried a 270, (several) 30-06, 300 wsm, 300 win mag, 300 wby mag and a .50 cal front stuffer for elk. I've killed elk with the 50, 300 wsm and wby, and 30-06. Never came down to anything except "I want to use this gun". And now I'm putting together a (hopefully!) 5 lbs 308, a 375 Wby and a 7mm-300 win....because why not. Guns are fun. I wish I could hunt 6 elk a year so I could use MORE different guns. Never felt under nor over-gunned with any of them. Shoot what you want, as long as you shoot it good.
