In learning how to use an old Ideal steel 310 tool in 30-06, I have all the dies adjusted and running well except for the expander plug. I tried using motor mica like I do in my bench mounted presses for lubricating the inside of the case mouth, but couldn't pull the Ideal expander out of the cases very easily. The old Ideal Reloading manual I have (No. 39) says to use some oil on a pad and touch the case mouth to it to put a little oil into the end of the case mouth to lubricate the expanding plug. But it didn't say what kind of oil (wale oil?) or how to clean it back out before loading the casing. So I tried a little gun oil on a clean rifle cleaning patch on a cleaning rod to insert it into the mouth of the case and twist it and pull it back out. That seems to work ok as the expanding operation was much less of an effort. How do you 310 users lubricate your expander plugs and clean out the cases before loading powder?
