I am very experienced at reloading, but have not encountered this problem until I tried sizing auction bought "once fired" 223 Rem cases. These are commercial Remington headstamp cases. I am using LEE dies and shellholder. I am lubing the outside of the case AND the inside of the necks. I deprimed them using the LEE universal decapping die, then cleaned the cases and scraped the primer pockets before attempting the resizing operation.
Once every 5, 10 or 15 cases, the case will hang up in the die, and pull itself off the shellholder in the press. This forces me to release the decapping pin/expander ball from the collet, and pound on the decapping pin to dislodge the shell casing from the die. THEN I have to mount the decapping pin/expander ball in a vise to pull the case off of that! After a couple of these, I have to grind the peened end of the decapping pin/expander ball to fit the collet.....It is getting a little annoying.
I have just about decided to give up on these used cases, and buy a couple hundred new cases. I am reloading for a single shot, so it's not like I need to load up 1000 rounds ......
Would a different brand shellholder hold on tighter?
Is this a common problem with this type of used case? The ones that hang up do seem to require a lot of pressure to size in the die, but by the time that is discovered, the case is already in the die, ready to stick.....or maybe not....
