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.
