.223/5.56 NATO Hanging Up on Case Feed Arm Bushing

About 50% of the cases stop on the edge of the CF arm bushing (green #13412) and do not drop into position for Station 1 insertion. I am using the white CF adapter.

I have: reinforced my bench to make it stable; slowed my cycle rate to a crawl to observe what may be happening; and, had my wife try to observe what is happening while I slowly cycle the machine.

I appears to just drop from the CF adapter and case feed tube at a slight angle and catch the CF arm bushing at the lip. An extra step of tapping the stopped case with the tool head at top position, drops it into place. However, this is a distraction.

Any suggestions? Thank you.

Was the machine previously in a different caliber, or always in 223? Can you send some photos to sales@dillonprecision.com ?

It was in 9mm originally. I will shoot some photos this week. Thank you for the reply.

Photos sent.

Photos received. Push the white case feed adapter down until it is fully contacting the top of the feed body, and push the green plastic case feed arm bushing down so it is flush with the top of the arm. Look for a burr on the outside top of the arm bushing that could be preventing it from sitting deeper in the arm.
