FYI
You can cut off & use the fingers & thumb of latex exam gloves along with a rubber-band to keep rain & snow out of your barrel. The projectile will shoot through.
Good luck hunting all you all.
or you can use Seranwrap that sticks to the barrel nice and place a rubberband around it. I use that on my FL barrel and also for a cows knee over my frizzen/hammer in the rain snow of Penna late season FL only. Chap
