Agreed! IMO, there's really not much need for any magnum cartridge to hunt anything in the lower 48. I've used 'em years ago, and enjoyed shooting 'em. Still do, especially like the 375H&H. But, to start off with folks should get well acquainted with a good 22LR. Then, for a first centerfire deer cartridge try out a few at the local ranges. Most, I think, would do well to go with the likes of the 6.5x55, 270Win., 7x57, 280Rem., etc., or evena 30/30. Heck, for deer you really don't need anymore than these provide.
7mm-08 or 308Win. if you want a short action.
