I used Browning supers for years in skeet matches. A shot of WD40 prevented rust in the barrels. When you hear fellow shooters dog WD 40 remember that they are talking about it as a lubricant. I have used it with great results as a rust preventive here in LA. Believe me a day of shooting in 98/98 will rust most guns if they are not protected. temp = 98, humidity = 98 That build up is rust preventive it stops rust but is not good as a lubricant.
