Was wondering what the thought is and if it might help on adding some form of additive to the tumbling media to help on possible more consistent neck tension. Thanks Bill
In total agreement with Jon here.jonbearman said:What kind of tumbling media do you have? Tumbling has really nothing to do with neck tension unless it cleans all the carbon off the interior of the neck of the brass,which will make for heavier seating pressure.
