I dislike priming on my Rockchucker too. I bought the priming tool for it and tbh I'd like to shove it up the engineers ass who designed it. Might make a fun childs toy with all the hunting and pecking away at primers but beyond that it belongs in the trash. It works acceptably once adjusted and filled. Problem is I'm sick of it before the first tube of primers is loaded. I have an older Lee hand primer with the square tray that is still going. It has never let me down, although it sometimes flips the odd primer. Easy fix. I have the Lee bench mount primer since I already have a lot of Lee priming shellholders. It was steaming crap out of the box. The new primer tray should be shoved up the engineers ass. His luck, it would probably pop open when he didn't want it too and make extraction as frustrating as trying to use it on the priming tool. A just reward, IMO. The mechanical chunk of plastic that controls the feed of primers is not qualified for its job. It often requires I pull the handle down and let it fling back up to jostle a primer through it. It has gotten better but still F's up every now and then. Feel is ok, not great but certainly effective. I have the FA handheld priming tool. I believed the marketing about consistent primer seating depth and have another request to shove something up the offending engineer's ass. Both seating depth and the adjustments are no more consistent than seating by feel and the adjustment wheel is not true. Every half rotation it loses detent tension and freewheels. Atleast the primer tray doesn't suck on it. Maybe I'll try an RCBS handheld next. I have no idea how I'm going to track all these engineers down or how lengthy the court proceedings for each warranty return will last but if I can just find a priming tool I don't hate maybe I'll leave the engineers alone.
