"...worth buying?..." Find ammo and brass first. Even if you don't reload now, buy as much brass as you can, dies and a shell holder when you buy the rifle. The assorted marketing depts can and do drop cartridges with no regard for their existing customers regularly. Having brass, dies and a shell holder means you'll never be caught with a rifle and no ammo.
"...which is dang near a 8mm Mauser..." And? Nothing special about the 8mm Mauser.
Pretty sure that 308 brass and shell holders will always be available.
The 8mm Mauser is a very fine all around cartridge with moderate recoil. There are other cartridges the same could be said of as well.
