definitely a good cleaning is in order and glad to see you took it fully apart,

one thing I notices was the ramp seemed like it had a bigger gap meeting the ram, look at this picture I found

when you say "with hook instead of the wire gate" are you talking about the metal wire that goes out, over the top of the primer ?

on the new machines (and new rams) that wire is no longer there, not exactly sure what it's intended purpose was, the ram on my 800B machine is like that also,

Do either of you use the new Wave primer tray?

I have two 800+ and a 800B, I don't use the wave unit, I've never really had any primer issues, either from the tray to the ramp to the ram,

The 800B was old and abused, it took a little attention to get it right but after that, no issues on a basis, maybe once in a while I'll get a tilted primer on the post or maybe one that doesn't want to feed to the ram but they are rare,

it seems the movement of the handle is enough vibration to keep them falling into the ramp and as long as the ramp is at least 1/4 full, it's enough to push them in the ram,

I would say I exclusively use cheddite's, almost 18k so far, ( the blue/pink box, not the old yellow ones )
