i was able to decap about 100 with a lee decapping pin before realizing the flash hole was smaller. I recently started reloading on a progressive and was having issues with my flair / expander, so I thought the sticking was on my second stage. After my Lee pin broke, i realized it was the flash hole.
i just throw Norma brass out now. its a shame, I have a few thousand rounds I was collecting to reload.
