just about anything in 308 will do the job - same deal for 06, and unfortunately, there's a school of thought that says you NEED a 338 win mag and 250 grain solids for elk- i happen to disagree with that- 308/180s will do all that's necessary and then some, if you PLACE YOUR BULLET PROPERLY- main thing is to get some quality trigger time and not just on the range, unless your range is out doors
