That's the newer FA seater, it works fine, used it today. I had the original version before, and the depth adjustment mechanism froze up. They replaced it with a whole new kit with this newer version. I suppose I wasn't the only one who had issues with the original design.
I've worn out a couple of RCBS hand primers and they've replaced them each time. They're a little flimbsy and the plastic inserts wear out or warp over time, especially the small primer setup. Mine would load a SR primer up the chute but it would rotate the primer sidways halfway up and try to seat it sideways in the primer pocket. I have a new replacement on my workbench right now as a backup dunno it it works yet.
