Yup- but don't you want to remove the grease from the chambers and barrels before you fire the gun? I sure as heck would. I still have a old tube of RIG gun grease- my Dad used it to keep his firearms safe from rust in the "off-seasons" we didn't have steel gun safes and heat lamps in my boyhood- Dad stored his on open racks up in the attic-- 1950's era--
