In the spirit of trying to get back to the OP's question, I wouldn't hesitate to put a 7-08 in the hands of a young shooter. 7RemMagnicifent? Not so much.
7-08's and 120 BT's are mild-mannered, game killing machines (killed nearly 50 whitetails and more hogs than that with it). A 140 Accubond or partition.....lights out on nearly 40 aoudad sheep and about that many whiteys and mule deer with that one out to 300 yards or so. Obviously the 7RMagnificent will do all of the above as well, with more recoil. I cannot think of a better cartridge up to medium size game than the 7-08. I wouldn't hesitate to use it on African plains game either, at least up to eland size stuff.
