my issue with the fl bushing dies is that you can't process mixed or thinner brass.
I have a forster custom honed die that works only for lapua brass.
When I use it to process thinner brass, bullets fall through.... so I have to double-process cases through a lee collet die after that.
It's a bit of a pain to process 308 brass this way, so it is possible that I will eventually just buy a conversion kit for my xl650 and setup the dies on it, with one shellplate for loading, and one shellplate for priming/seat.(with weighted charges)
When you get used to the 650, it becomes very annoying to handle brass 2-3 times.
