Got a Traditions Crockett for Christmas. Finally got a chance to shoot it last weekend. Cleaned it with Ballistol and water. Been running a patch covered in Ballistol down the bore every day since. I get 2 black streaks from the same groove every day. I scrubbed till all the patches came out clean and the next day 2 black streaks again. Has anyone had this happen? I'm thinking it might just be some of the factory grease that didn't come out the first time I cleaned it.
