the 7mm mag is in no way over kill for anything i have shot deer at 20 yards with mine and there was no meat damage where my 270 hasin the past wreaked alot of meat on game. but you can if you do it wrong have a mess with any gun 7mm if you can see it you can hit it thats what i like about the 7mm accuracy and long rangeif your going to be hunting only in the bush go with something different 30-06 or maybe a 270 but if your hunting openlasnd and cutbloks and stuff why not be set up for that trophy buck 500 yards away that you cant sneak up on because it has your seant and its looking straight at you. all guns will do the trick but some will do it easier. but the main thing is like find something you really like. research every calibur you like like the 270 the 30-06 the 7mm mag and throw in a few you never thought of like a 243 or a 6mm or an 8mm the 6mm and the 8mm will be hard to find ammo for and if you like the wsm' well id sudgest looking at the 270wsm i have been looking at it myself but i cant justify it because my 7mm mag is a lil better out at 800 yards. do the reasearch what stands out and you like the most go for that cal dont just look at the bullet trajectory up to 400 yards go to 800 or better alot of bullets will be close and look the same to 200 yards and to 400 yards find out whats best for you. my grandfather shot a 7mm mag and i reasearched it for years before i bought one. well do some serious research on the cals before you select one.
