If you reload I would say a 28 Nosler, just because I like to be different lol but in my eyes 300 win mag and 7mm mag will be 6 in one hand half dozen in the other. Both ammo you can find everywhere, both do great out to long range. If you don't reload and still want to poke at distance I would look and see which one has a better bullet selection in factory ammo at shooting at distance. Both have been proven time and time again....
But in all honesty if it is for elk and deer under 400 yards I would just pick something like a 30-06 or something along those lines. To me, with bullet technology, you won't reap the benefits of a magnum caliber unless you are hunting at extended ranges and reload. Because today you have stuff like Hornady Superformance that is pushing a 180gr bullet at 2820 fps and compared to 300 win mag Hornady standard factory load the 180 gr bullet is going 2960. Not much of a difference for me to justify buying a 300 win mag unless you reload.
