Metal shavings on Dillon 550

[safenate]

i have some very fine (dust) shavings on the first pin on the shellplate and the surrounding area. It is near the powder funnel, but lighter proved it isn't ground powder. I don't do much lubing or such. Any help is appreciated.

Are you using an EGW U Sizing Die? I get brass shaving on occasion and its from the U die shaving the very bottom of the case.

I am using U die, but it doesn't look like brass. It looks like steel or alloy.

I get this as well with the large primer system when I am loading .45ACP with ?X fired range brass. Close observation has shown me that it is usually from the paper clip(?) pusher that is used to hold the brass in place being slightly out of whack, causing the decapping pin to shave small slivers of brass out of the primer pocket.

The only other place I pick up the odd shaving from is on station 2 when expanding the case mouth/powder drop, you may have a few weak pieces of brass that won't take to being expanded again, and will shave slivers of brass off of the casemouth.

Hope that helps,

Chris

I have found semi circular shavings of silver colored metal which I think are shavings of the silver colored primers caused by the shell plate being ever so slightly out of perfect alignment when priming the case. I use a 550. Not sure how to fix this however and it does happen fairly often to me.

Try tightening your shellplate bolt more. If the plate is loose, the case is held at a slight angle when the primer is seated,

causing the edge of the primer cup to be clipped. This leaves feint crescent moon pieces.

Thank you for the suggestion... will give it a try!

I get cresent shapped brass slivers in the primer cup area if some 45 military brass with former crimped primers slips into my mix of brass. Best to avoid crimped primers or swage the pockets.
