I thought this thread was about the outside neck cleaning??? LOL...why I emphasized the outside so it would help others if they searched this.
Jeff, have you ever seen the need to put some type of lubricant on the inside of the necks to aid in bullet seating? I have read that when all the carbon is removed the neck can become "sticky" when seating a bullet and some type of lubricant such as graphite needs to be put in the neck so your seating depth doesnt change, so you dont get runout issues, and so consistant neck tension is achieved.
