Hello everyone. I went out hunting last weekend and it was rainy, spent the night and came home the next day but after i got home i cleaned my gun but found some rust spots on the bottom of the magazine and the edge surrounding it. i tried to clean it off with some cleaning oil and got some off but you can still see it. i was wondering how i can get rid of the rust? its a savage 116 ss. help and any help on preventing rust in the future is helpful. still new to maintaining/ cleaning guns.
