Got to tryout my automatic primer on my MEC. Remember this is a single stage press. Takes a bit of adjusting (but then what doesn't) and it does OK. Every so often you don't get a primer but you can hand cycle to get it.
Did have two areas of concern:
1. The new reprimer punch is hollow and the auto primer tray fits on top. I had to open up the tray housing and reduce the diameter of the punch to get them to mate. The combination was too large for a good fit.
While I was at it I radiused the inside of the punch so primers wouldn't hang up on its sharp lip. Ran the punch up against a 1/2 drill bit then some wet and dry to smooth it out. No problems now.
2. In the up-date kit you get a flanged nut. No where in the directions does it tell you what it is for. When I email MEC they said it was to replace the nut on the first station--the depriming one. Would have been nice to know that at the beginning.
Other than those two minor concerns it does seem to add to the fun of shotshell reloading.
