I have had satisfactory results, but I find on the dies I have the expander plug is too short and you really have to crank down on the top nut of the FL die so the decapping rod stays in place. Plus if you bend the pin, you have to replace the entire rod.
I guess you get what you pay for though.
Could part of the problem be the expander is having to go back out of a neck that has been sized down a good bit more than necessary? Have you ever measured a neck sized without the expander in place so you can see how much work the expander is having to do?
