I was prepping 223 cases yesterday and had a case stick. I had run about 150 when it stuck. I had to pull the decapper/expander and drill and tap the shell for a 1/4x20 bolt. I use the bolt with a nut and a 1/4" drive socket to pull the case if it wont tap out with a steel rod. I cleaned the die and the next one stuck. Went through the routine again and tried a sized case which stuck. 7 cases later I let it sit for an hour. Went back and it is working fine. Maybe it was tired and wanted a break. I run my sized cases through a shell checker and I am finding a good percentage wont drop quite all the way. I reject those but am a little puzzled about why it is happening. I tried running them through the sizer again to no avail. I have run several thousand rounds through that die. I ordered a new one to be safe.
