My guess, you didn’t have the die set low enough to fully resize the case and the neck just started to get resized but not fully. I bet if you screw that die in another turn or so you’ll not have this problem.I actually did a full resize because some of the rounds were getting tight to chamber. I am wondering what I did wrong with the full length die that my bullets were loose. Never had that issue when I neck resized.
Wish I had read this before I dumped all the powder out. Oh well.Remove the decapping pin when ya resize again and leave the primers in place. Ya won't be out nothing but time.
