Never fails.....I was taught years ago to clean then resize, now the rules change, dirty case is better in the resizer.
Resize then clean....I think everybody can just do it whatever way they please! The conflicting reloading infomation just never ends does it?
For the record , I run fired cases thru the tumbler then resize, prime and load. Media will clog primer pockets and flash holes....but thats just the way I would rather do it. Never had a problem with clean cases resized in a carbide die. But I use treated walnut hulls with a little car polish added and the car polish may act as a light lubricant.
People who clean with water and detergent may be having the problems.
