I bought one of the Lyman Case Prep Xpress multi station brass prep
machines from one of the big reloader companies last winter.
Did not have much of a chance to use it till I got ready to load up a
bunch of rifle rounds to practice for Highpower season.
It does not take much downward pressure on any of the 5 stations to
make the machine just jump track and skip and jam for awhile.
Removing the brass shavings collection receptacle allows you to view
inside machine while running with a high intensity surefire flashlight,
revealing that there is a central plastic drive gear, surrounded by 5
plastic prep stations that slip out of engagement with the slightest
pressure.
The entire housing is plastic and allows too much flex of the stations
relative to the drive gear.
I have contacted Lyman with no response.
Save yourself some money and stay with the twisty, turney way of prepping brass because this thing is a $100 piece of junk.
