I like using Lee neck sizing collet dies as you don't have to lube the cases or wash it off afterwards.
Came to the earth shattering conclusion today that you cannot expect the little BSA Martini's to eject a case which has been neck sized too many times.
The 223 cases had been fired four times and then neck sized three times and just didn't want to eject and I had to use a Cleaning rod to shift the fired cases at the range. Tried them again at home this morning with a clean dry chamber and they still would not eject.
Then tried it with some full length sized cases and with the slightest touch of the ejection lever the cases extracted.
It was a wet day at the range yesterday and I made sure of taking every thing apart when I arrived home to make sure every thing was clean and dry but why is it always the case that when you drop a screw or something else small that it always falls behind your work bench out of sight?

It is one of life's unanswerable mysteries how small parts always bounce into oblivion when dropped on the floor.  Watchmakers have been known to wear an apron which is also attached to their work table.

On the lost parts problem - I use a rubber floor mat with generous recesses that catches and traps stray parts.  Saves a lot of time and frustration.
