Long ago I stopped using RCBS lube & pad and also Spray lube, been using Imperial Sizing Wax for the past several years with complete satisfaction. Wipe on the case exterior with fingers and inside the neck with a Q-tip, after sizing a quick wipe with rubbing alcohol on the outside and alcohol moistened Q-tip inside the neck and I'm good to go. Tumbling before sizing is accomplished with hot water, Dawn dish detergent and Lemi-shine. Rinse with hot water after tumble and let air dry.
