If I am between shooting sessions and it may be a week or two before I get back out, I use Rem Oil, in and out of the barrel..IF I am not going to shoot for an extended period of time I use Birchwood Casey Universal Gun Grease to protect the bore of the rifle, and Rem Oil on the outer metal parts.I second the suggestion of swabbing inside the barrel with alcohol or brake clean, ESPECIALLY after using B/C Universal Gun grease.Doing this also reduces your chances of hangfires and misfires due to moisture in the barrel.
