At the Wholesale Sports Pin Shoot in Selkirk, every year, guys bring out their mostly bolt action rifles, and fire continuously for up to 10 minutes. Last year, I ran 35 rounds of 22-250 in 6 minutes and my partner did about the same. Which is about par for the course. Lots of fairly expensive custom rifles in attendance. I doubt any of them make a habit of it, but every once in a while, it's not going to seriously hurt anything. Hell, the winners last year, would have been fools to accept my car in trade for their rifles, and they didn't bat an eye at shooting them like madmen for 3 minutes.
The first year I attended, one member here, finished in second or third, using a pencil barrel stevens 200. Mirage from the barrel was practically blinding him by the end, but he kept chugging away and finished very well, so accuracy was still acceptable to 200y, even through a barrel so hot that it could likely have been bent by a strong man with asbestos gloves.
