The butt plate on my 10/22 stock is slick plastic. That never seemed like a problem until last weekend's Appleseed shoot. Now I realize it's an advantage to have the butt end of the stock firmly "stuck" to my shoulder in seated and prone positions. The chicken wing makes a good pocket that holds the stock firm while standing, but I noticed it sliding too much when shooting from other positions. What's the best way to give that slick plastic butt plate some adhesion?
