New APP owner. Have had it running for a few days decapping 223 and its been doing pretty good. Took a bit of tweaking of the adjustment of the Lee Universal Case Feeder and the APP's Pusher/Slider and put some carnuba wax on the slider rails. Also stiffened the Slider Spring internally with a piece of a WD40 plastic spray tube.
A couple of glitches remain - one is I'm getting primers hanging up/not dropping when punched out and not allowing the next case to push the problem casing out & advance into the shell holder despite my believing the decapping pin in the Lee Universal Decap Die set correctly. Pin is nearly new and is set flush with top of die and die set so APP Handle when pulled down ends up parallel to the floor. Issue seems to affect crimped primers more - Lake City 2000 headstamp was problematic whereas I ran close to 1k of PMC non-crimped without one hanging up.
The other is frequent misalignment of the decapping pin with the mouth of the 223 case mouth, requiring fiddling with the casing to pass the pin through. Shell Holder (#4) turns freely but seems to have excessive front to back play/slop that may be causing misalignment issue? I know Lee has guided decapping pins - maybe I need to get some?
