What rifle?
You guys are cracking me up! Some great posts. I've hunted out west for almost thirty years and have taken lots of deer and elk and the occasional moose, goat, and bear. In all that time I've taken only one animal from over 500 yards. 90% of my rifle shots have been under 300 yards. Too me, caliber and bullet don't matter much if you're not completely comfortable behind the scope. Find a rifle that fits you and doesn't make you flinch and you will be fine. My personal favorite is my Browning A-bolt in .300 win mag.
