30-30 or 7 mag, hmmm....havent lost a deer with my 7 mag yet. (Knocking on wood) My Friend uses his not so trusty 30-30 and lost three deer in three years. One time in a hurry I grabbed our 25-06 and shot a buck at 200 yards and watched it run another 200 before piling up. I rather have them drop on site so its 7 mag for me.
