Whatever you use be careful! I used tape on my Mossy 835 5 years ago for Turkey season also. Yea, then it rained. Pulled the tape off a few days, a week?, later and the barrel was rusted beyond my fixing capabilities. I took the gun apart, stripped all pieces, cleaned, primed and put a nice camo job on it with my airbrush. Came out pretty good. Just watch out if the tape gets wet.
Hey, did you grab the blind bag with the shells when we left the truck?
Safetys, use them: If you can see red, you can get dead!
