I currently have a Winchester Pre64 in 30-06, which has mostly been used on Deer. Thinking about taking a trip out west to go for Elk. Some of my friends have told me that I should get something a little heavier than the 30-06. Also, looking to go for Moose in Maine or Canada next year. Checking the ballistics on the 180gr 30-06 and the 250gr 358 Win, it seems that the 30-06 packs more energy than the 358 Win - surprised me! Am I looking at this totally wrong? Would appreciate some feedback.
