I used to use the RCBS ink pad system, but for me it's just too messy and I still have to lube the inside of the neck by hand. I started using the Hornady One Shot and it works best for me. It works , but you MUST shake it well first and allow to dry or you'll get cases sticking in the die. If you follow the directions it works beautifully since you can spray right in the neck to lube the expander when you pull out of the die and not worry about contaminating powder or primers. I let mine dry in front of the heat register in the winter and out in the hot sun for about 10 min in summer. Drying and shaking the can is critical.
