My son has decided he wants to go hunting with me this year so I have to get him a rifle. I took him to the range and my spare 12 gauge kicked him like a mule causing him to shoot high every time. He will be hunting in PA where you can use most any caliber for big game.

I think a good starter rifle would be a .270 Winchester. Flat trajectory, lightweight, and little recoil. We are hunting mountain mules in rocky terrain and do not expect any shots greater than 150 yards.

What is everyone's favorite deer caliber and why?
