I have never shot a a elk but if I were to hunt them my Rem 700, 3006 is the gun/ caliber I would use. I see so many debates and endless time taken up on this subject. So, here's my 2 cents. 3006 would be my choice, Decision made, with that part done I would practice a lot, shooting positions I would use in the field, prone sitting, standing kneeling. find an acceptably accurate load / with an decent bullet and know my drops out to 400 yards. I would hunt hard and not worry about equipment and what the other guys are shooting. Last I would use all of that extra time addressing the many other issues in my life that are in need of thought and possibly resolution!
