you need to take the barrelled action out now and again, and generously apply a good wax like that from trade secret, then buff it of course, but it keeps moisture and rain out. then after a soaking, you just run a few sheets of kitchen towel under the barrel to absorb and leave in a warm room to dry, not 'hot' room, just warm. otherwise, take the barrelled action out and dry it properly, tighten and go shooting again, if you tighten the action screws with a torque driver at 30 inch/lb, it will not change your POI.
