Winchester M70 is an excellent choice! I too, would recomend the 7MM RM! It is tried and true, and will be here long after the latest superdupermagnum craze is forgotten! I'd go even further, and say get the .280 Rem. and save money on ammo. For all but the largest, badest, North American game, they won't tell the difference between being hit with a 7 mag or the .280!
