This year's deer hunting has been unusual in my part of WVa. Almost nonstop rain for two days and warm. I know about using painter's tape to keep rain out of the barrel but what's the best product to protect your trigger? My son's Model 700 trigger really got rusty and made the safety really hard to put on fire. Took the rifle apart and the trigger was a mess. Know there are people on here who hunt in the rain on the west coast and Alaska where it rains almost everyday. Suggestion please?
