Never say never... after about 25 years and tens of thousands of rounds it finally happened.
The point is not how good or lucky you are. It is about the time you suspect there might be empties in the lot - what you do. I tried the funnel, for me it doesn't work - maybe my head is too heavy...
I have the Lock-Out die coming, and will try it, but I would have to re-arrange the dies on all the presses, and besides, I have total of about 9 complete heads... or ten... meaning ten times $55 (including shipping) for Lock-Out dies.
That is the price of yet another Glock.
Anyway, it took me just several minutes to sort through 200 rounds of .45's with this device, which I already had.
