Re-sizing and decapper die.

Was running some brass yesterday when the long pin inside the die that runs through the shell and resizes and decaps the primer pulled loose from my die and became stuck in the brass. This really angers me was there something I was doing wrong.? I used a small bit of resizing lube now I have no clue on how im gonna get it back in the die and how its gonna stay there. Any advice?

Re: Re-sizing and decapper die.

I'm assuming the expander got stuck in the neck and I'd say the root cause was the inside of the neck was not lubricated enough. Your decapping assembly probably has 3 parts, the decap pin, expander ball, and the shaft (either threaded or smooth).

What damage if any was done, did something strip out? All those parts are really not expensive.

If the neck is lubed right there should be a firm pull through it, no sticking or squeeking. If there is sticking your bullets will not be concentric (centered and straight with the case, runout). When the neck is expanded with the ball it is not kept in alignment by anything so the sticking will force the neck to cant off center a few thou.

Not needed for hunting accuracy but neck bushing dies and neck turning eliminates runout caused by expander ball.

Re: Re-sizing and decapper die.

You need to clarify what got stuck. My impression is that the decap pin stuck in the primer flash hole. If that is the case, simply put the case in a soft jaw vise, and tap it out backwards with a small punch and brass hammer. I have had that happen often. I usually reinsert the pin in the decap stem, tighten the expander ball, and grind about .001" off the end of the pin over the last 1/8".

Sounds like the decapping pin came out of the stem. You didn't due anything wrong. Re-insert and re-tighten the part that holds it in place.

Re: Re-sizing and decapper die.

I've had it happen to me on my RCBS dies. I reload a bazillion rounds of .223 during the year for plinking and training. It happens. Just re-insert and tighten up.
