Bob Allen Intercept Gun Case
Both Bob Allen and Birchwood Casey make gun cases with Intercept technology, which forms a reactive copper barrier to corrosive gases and moisture. You don't need to oil your rifle or shotgun--just stick it in a case, zip up, and walk away for 20 years, at which time you may or may not need a replacement case. I took both companies' versions and held them over my car's exhaust until their interiors were like miniature rain forests, then took 7-inch bare steel nails and zipped them inside. These nails will practically rust as you watch them, but when I opened the cases a week later--not a speck of rust did I behold. That's good enough for me. The Bob Allen case is the better case per se, so it gets the award. $60; 800-550-2698; boytharness.com --D.E.P.
