Welcome to the darkside young apprentice.... :grin: Anyway, Lyman puts on some packing grease into and around the barrel so that there won't be any rust by the time it gets sold and used for the first time by the new owner. Remove the nipple using your nipple wrench first. Pick up a can a brake cleaner at the local auto parts or hardware store then spray some down the barrel (with barrel removed from stock first) and on the outside. Wipe off the outside and drain the bore using an old but clean rag, repeat and then run some cleaning patches down the bore to see if you've got it all out. Do it again if there's still some grease in the bore. Once you are done then use a rust preventative on all metal parts and you're good to go. Prior to shooting your rifle, run a cleaing patch dampened with 91% alcohol down the bore to remove any left over oil that could affect the powder charge. A cleaning patch that is dripping with alcohol is not what you want, just dampened.sawandhammer said:i need to just put some degreaser or something down the barrel and brush the heck out of it to get all that crud out so i can play with my new toy. the instructions said to soak barrel overnight with wd40 then scrub in the morning. joe at lyman told me to use a strong degreaser. so there is a little confusion there as well.
