Your kinda putting the cart before the horse.
If your shooting factory ammo,you won't come close to shooting 4K fps,and you'd probably have blown primers in a handloaded cartridge before you get that fast.
Shooting a rifle with a hot barrel does more damage to the throat than shooting a hot rod load,although shooting hot loads will damage a throat faster than shooting a normally charged load.
If you are planning on handloading for your rifle,and use the listed data in any reliable reloading manual,you have little to worry about damaging the barrel of your gun for several thousand shots.
