Maybe your building a 300 mag. Because the 30 caliber is considered the American caliber.
Or because it's the classic western loading and just mention of it brings visions of tall snow tipped mountains. With a hint of the smell of burning quakies from a distant campfire.
Or because it's an accurate cartridge that will reach out there and cold hammer an elk further than most can realize.
While my favorite remains the 7mm mag. After shooting a few elk with both I have to say my favorite elk round is the 300 Winchester Magnum.
There's plenty of room in my gunsafe for both.
