Does Barrett recommend firing corrosive ammunition?
Barrett does not recommend shooting corrosive ammunition. Damage to your firearm may result. Damage due to firing corrosive ammunition is easy to detect and is not covered under the warranty agreement. However, if you have been forced by necessity or have accidentally fired corrosive ammunition, the following specialized cleaning procedure applies. As soon as possible after firing the corrosive ammunition, thoroughly scrub the bore and bolt face with very hot soapy water. The soapy water will neutralize the salts which attract oxygen to the steel surface. When the metal is clean, rinse the surfaces with very hot water. Wipe off excess moisture. The residual heat in the metal will evaporate moisture. Either continue cleaning the rifle using procedures specified for non-corrosive ammunition, or if temporary transportation or storage is necessary, coat all surfaces with rust preventative or light oil.
