[QUOTE="bob4, post: 1157746, member: 57171"] I read something either on this forum or another about a build up of media and polish (like Nu Finish) on the inside of necks. Sure enough when I took a close look at some of my 270 necks they certainly had some of this build up. No doubt in my mind this would have an effect on accuracy and if there is build up on the walls also, less case volume and same load means more pressure. As I looked at my tumbler last time I refreshed the media it showed the same build up. Wasn't sharp enough to put 2 + 2 together.:rolleyes: Now I'm wondering how much build up is inside my case walls? Considering going back to wet tumble or forgetting the Nu Finish. I use about a cap full per load in a Lyman 1200 tumbler. [/QUOTE]
