The right amount of lube is something you learn with experience. It does not take much at all. I have dented a few in the last 50 years but nothing to get worked up over. The only stuck cases I ever had were with spray lube. After clearing two stuck case problems the spray lube went in the trash. I have always used RCBS lube and as long as I pay attention no problems. I also just load the dented cases like any other. No problem there either. However I honestly have never dented any as bad as the pictured cases.
