Here is one that all you have to do to get is go into the pharmacy section of a grocery store. Silicone personal lubricant. $5 for a 4.5 oz bottle. 2 drops on a pice of a shop towel, and a drop or two on a pipe cleaner. Rub you index finger on the towel every so often, then wipe the case neck, and shoulder. use the pipe cleaner to lube inside the case neck. When done sizing wipe with a touch of denatured alcohol, or tumble for a few minutes. Use a dry pipe cleaner to wipe inside of the case neck. I gaurentee it wipes clean quickly, and no lube dents at all. I can 200 cases in about 30 minutes without rushing it.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
