shoot whatever you feel like. i've been shooting my 7mag forever, and have killed the vast majority of my deer with it. i'm not especially loyal to the 7mmRemMag, just that gun. my dad gave it to my granddad, and i got it when he died (when i was 5). i'm beginning to go out a lot more with the .243, the .30-30, and the 98K Mauser in 8mmMauser (the .243 because of the lack of recoil, the .30-30 for really thick areas, and the Mauser for the novelty). the point is, i'm not an especially big guy (5'10", 160lbs) and i'll shoot anything, therefore you should be willing to shoot whatever you can get your hands on.
