I agree; they'll last for less than 600 rounds with the huge powder charges they use. Double the charge weight for a given caliber and barrel life drops to one fourth or less as many rounds.
The three .30-.338 Win. Mag. barrels I wore out shooting 'em once every minute or so for 20 to 30 minutes lasted about 1200 rounds each. But they burned 50% more powder that a .308 Win. and that's the reason their barrel life was so short. Folks shooting 7mm Rem. Mag's the same way got about 800 rounds of barrel life.
