I bought one of these after prepping hundreds of once-fired military 5.56 by hand and the ensuing finger cramps that came with it. It has definitely helped speed my prepping process up with the relatively large amount of non-precision 5.56 I reload on my single stage (plinking ammo or ammo for short range 3-gun, etc).

However, I started getting into the bolt-action world a couple of months ago and really looked at my setup for the consistency aspects of my precision .308 loads. I have found that the little attachment-holder cylinders that spin seem to be slightly off center. In other words, the various trimmers, chamferers, cutters, etc. do not move on one single axis, but rather seem to wobble just a hair. My big concern with this is the fact that it could allow for some slop in my primer pocket uniformer, flash hole de-burrer, and chamfer/debur attachments.

Is this entirely normal for the machine? I would think that it would be impossible to "uniform" something like a primer pocket if the machine used to uniform it wobbled back and forth unlike a drill press, etc. that has a very precise rotation. Another big concern I have with this would be that I'm somehow "uniforming" my primer pockets just a little too much. Because of the slightly off-center rotation could I have issues with primers seating consistently or slightly backing out due to sloppy tolerances between the inside diameter of the pocket and the outside diameter of the primer?

Or am I just overlooking the whole aspect too much?

Thanks for your help.

It's normal. Also every month or so tighten the alen screws on the bottom if it. They vibrate loose

but ask your self this. What holds the case on the perfect axis?

Good call, haha. Never really thought about it that way. Thanks for the quick reply and the advice about the allen screws on the bottom.
