I don't think that is a silly question. My take on it, with no experience in this area is; When culling I would think you would be firing multiple shots repeatedly. Now this would not be a one off situation. I do not know if doubles are able to take this sort of work over extended periods without shooting loose. Most bolt actions can take being worked that hot that you can't touch the barrel-sure the barrels will not last as long as they would if not shot this hot.

Other factor is how many who cull can afford a good reliable double?
