I'm new to the hunting scene and I've been Elk hunting twice in Western Colorado and for this coming season I drew for an Antelope and will be hunting Elk later in the year. Previously, I had been using my friend's Rem. 700 7mm mag rifle for the elk and I liked it a lot. I was wondering though if anyone knew of a good caliber that I could use for both Antelope and Elk. I know that's a large range, but any advice??
