I have an old rock chucker, a Lee challenger, and now a lee classic cast. The old rock chucker was getting worn, so now I have changed its dutys with its replacement of the classic cast. To make them operate smoothly, I found that if you lube the pivot points and ram with stp you will reduce wear and get a much better "feel" when sizing and crimping.
No such thing as a stupid question. What is stupid is not asking it.
