Thread: Cases getting stuck!

Getting Frustrated now. Last time I loaded I got 2 stuck cases out of 100, this time the first two got stuck, and now the decapping pin is broke. What am I doing wrong?
the gear is:
Lee FL die
Hornady one shot lube
.223 rem once fired cases assorted brands
lee 100th anniversary press

I assume my lube is the problem, now I have broken the capping pin, and suspect I have done damage to the collet on the back of the die (through being a rough C*nt) Can I buy the de capping pin anywhere? Or would I need to get it in from the states? And what case lube should I use? Also, can I just use a crimp die rather than a fl die on a semi auto? or is it best to use FL every time.
