overheating a new barrel?

[r106]

He's probably having more fun than most of you guys are. Why should you care if he gets his barrel hot? He obviously doesn't.

I don't care.. It's not my gun LOL. I am fairly new to the shooting world and was always told "make sure you don't overheat the barrel" I just posted it because I got a kick out of seeing it..

It did look fun

if I see him there again I might ask him if I can try shooting it like that
