Apparently my 9mm seating and crimp die got out of adjustment. I had a very hard time extracting unfired rounds. Afterward, I did a plunk test with the barrel and indeed the rounds were maybe a millimeter from fully dropping in. During firing, the slide apparently had enough force to drive the cartridge in all the way.
My first thought was OAL too long (1.145) and the bullets getting stuck on the lands, but didn’t see any indentations on the bullets (RMR 115 gr plated). The only other reason would be that I didn’t take enough of the flare out of the brass. so, I am going to reset the seating/crimp die and see if that fixes the issue.
Lesson learned: plunk test the first couple of rounds when starting a reloading session and maybe plunk after every 500 rounds.
