I shoot and eject the case, look at the target with the spotter scope, load another round, repeat for 5 rounds. Change guns and repeat. I give it about 10 to 15 minutes between groups from each gun. I never fire a round from a barrel that is still hot to the touch.
Even with my heavy barrel guns 5 rounds will make the barrel hot to the touch. I don't know that the groups will get bigger after that but don't care to waste my ammo finding out.
Their is one exception. My heavy barrel 10/22 always gets 10 shot groups and the groups are around .5 at 50 yards which is acceptable to me.
