I've had several 7mm and 30 caliber magnum rifles over the years. I have no issue with someone using one if they want to, but after a careful assessment of reality sold mine. I have a couple of 30-06 rifles that I've had for decades with too much history to sell, but I came to the conclusion they were bigger than I needed for the vast majority of my hunting.
My primary rifles now are 308, but anything in that class, (7-08, 260, 6.5CM,or 7X57) would be just as good. With my handloads, or some of the better factory loads with todays premium bullets I'd not feel handicapped shooting elk at 400 yards with any of those cartridges. That is about the limit of my comfort zone when shooting at game, and elk is the biggest animal I'll ever hunt. The 30-06, 270, 280 class of cartridges would add a little bit of insurance by hitting a little harder. But I just didn't see where any of the magnums started to have an edge until you start taking 600 yard shots, and that is just farther than I feel comfortable shooting at game.
If I were going back to anything with "magnum" on the headstamp it would be one of the WSM's. I had a 300 WSM for a while and found it accurate, easy to load for with much more pleasant to shoot than 300 WM. Especially from lighter weight rifles. It won't quite match 300 WM speeds, but easily beat 30-06. I felt that the trade off of slightly less bullet velocity for less recoil was a good one. I don't see why 7mmWSM wouldn't be the same.
