I've tried searching and couldn't really find the answer... For 308 AR how many rounds is too many in reguards to overheating and potentially killing a barrel... I understand a gap 10 is a precision built and not battle rifle but in the case of rapid shooting, fast follow up drills, multiple target steel shooting, how much is too much? I ask now before being silly on a range day so I don't cry later.. I would hate to have wasted time of the wait and money for an very accurate system just from something that could have been prevented.
