What 7??? Sheesh give the guy a break, its well understood that when someone says "7mag" they mean THE largest selling magnum on earth. The 7mm Rem Mag!!! There are more of them sold than all the other "7s" combined. That was un-called for if you ask me.

Now to answer the question, for deer only either will work great on deer in most instances. Personally I would take the 7mag because of its versatility over the 270. BUT he asked about guns for deer didnt he? He didnt ask about the mythical "one gun for all" caliber. (LOL I'm becomming as literal as some of you guys!)

Good luck and regardless which one you pick you will be ready for the game!
