Yeah, there are impracticalities about owning a .300 H&H. If you don't handload, ammo is hard to find and not very varied, and even if you do handload brass can be hard to find.
Other than that, the .300 H&H works fine, but to turn your logic in the opposite direction, it doesn't do anything the other .300's don't.
