Ive had one for months and its my favorite priming system to date. Before this I primarily used the Sinclair hand primer or the RCBS bench primer with the primer tubes. The priming unit on the FA is made of metal and is heavy and very beefy. I have big hands and I have to stretch them out to lower the primer ram all the way. Not a big deal to me but it may be for someone with small/med hands. I like the fact that its quick and easy to change from small primer to large primer. Also the shell plates pop in and out in a snap. The machine comes with all the replacement shell plates you need right in the box. The Sinclair would take a few minutes if I had to change anything around. Sort of an annoyance. The primer feed system works great from the plastic tray. Once you get the right angle of the tray, the primers feed reliably. You can also adjust the primer seating depth as well which is a nice bonus.
It’s a solid system and I love it. I don’t foresee anything breaking so it should last for many years to come.
