Its always interesting to see my own comment from a while ago. Sometimes I find that Ive changed my tune. In this case my response is exactly the same as it was a year ago above^^. I live in Northern New England, it rains a lot, it snows a lot, its pretty humid. And I clean my guns at least once a year whether they need it or not. (Thats not really true, but Im not overly anal about it). Unless you are coastal and dealing with salt, Im not sure you’ll find too many climates that are so much harsher wrt rust. What type of “inclement weather” are you worried about?
