If it's doing that in the collet die then it looks like it's not entering the collet.

Hmm, looking into this a little further, someone else had the same issue witha .223 lee collet sizer, and he reckoned that it was something to do with ramming the press into the collet die with no cartridge causing the collet fingers onto the mandrel...

Not sure this applies here... but similar looking photos of the issue.

That is interesting, I'll have a look at my die but as the problem was intermittent I suspect it isn't the answer. Will report back.

if the piece that squashes the collet together, has not released from the collet when you drew out the previous case, then it would do just that, then when the tension is released back off as you withdraw, it could then pop free, or if you then inspected it, maybe it released then?

The collet dies really need to be cleaned up and deburred etc.
Polish the de-capping rod and use a bit of copper slip or moly grease on the collet taper.

+1 on this, strip the die, give it a good degrease, clean even a bit of scotchbrite will do, lube it and crack on better than new, the dies do pick up crud from the cases over time.

Throw it in the bin and buy a decent neck die.
