Dad wants to go on an Elk hunt in Colorado before I get married next year. I dont think my .270 would be enough to take down a bull elk (and im sure im going to open up a certain can of beans here) but if i go big bore rifle, i am looking at a 300 Win Mag. Anyone ever done any guided hunts near Gunnison? If so, what kind of range could I expect to take a shot at? Im comfortable taking shots at 3-400 yds with my .270 at paper on a range, (i know targets with a heartbeat are game changers) but im just trying to see if it is necessary to invest in a new gun....any advice will help.
