Upland hunting in rain sucks anyway, just dont go. I cannot think of even one, remotely successful day afield upland hunting while it was raining. Ive had many great days just before and after rain...but never during. Snow days can be good and your gun will look like it got rained on, but like the other guys said, who cares! Take em apart, clean em, dry em, lube em, and get them ready for the next day. For really nasty stuff, I have 2 plastic fantastics (Winny Sx2 and Beretta 390) that are both reliable as a Toyota. I literally drove over the Sx2 (short story, still embarrassing :-) ) and it took that lickin in stride.
