Ok guys here was my predicament last weekend. I have a sweet O/U Browning white lightning. It has shot flawlessly for me for the 4-5 years that I have owned it. Saturday it refused to fire. I couldn't get a firing pin to work. Got it home took the stock off of it and as near as I can tell here was the problem. When you break open an O/U it cocks the hammers and makes it ready to fire again. When I broke it open it didn't reset the mechanisms. I began to spray gun scrubber throughout the entire inner workings of the gun. Eventually it loosened up, and now it works fine. I have let it sit out on my bench and tried it again yesterday and everything still works fine. My question is what if any lubrication do you put into this part of the gun to keep it moving freely. I know that too much oil of grease will only cause the issue to come back. What have you found to be the right amount of lubrication to work in all temps especially cold weather and what will not just attract more junk to attach and clog the gun up again?
