I would think that if it didn't cook off it would be OK. That's just my hunch. I can't believe it would produce more pressure, in fact if it got too wet it might not work at all. Does he still have anything to shoot it in? For most of my life I have been paying a little extra for a gun rider on my policy. Of course, my agent is the kind of guy who keeps a (street legal) AK and a waterproof drum of 30 Commie around.
