I am going to CO as many of you are and this being my first time i have a few questions. Fist of all what is th best way to dial in the ranges for elk. I have 300RUM with the Leopold Long range scope along with a range finder. Is there a crtain way I can just find the range, say 400 yards, and dial in the scope so it will be dead on? Also, I know the accubonds are new, but would they be safe to use on elk? And should I need a bi-pod for colorado and if so, which is the best?
