The case should not be swelled because of the Lee Factory Crimp die. The OAL seems like the guilty party.
Light primer strike: I broke down the slide, the firing pin channel looks clean, nothing suspicious, dirty, metal shavings etc. The primers are seated on a lee turret press, every primer is consistently seated the same way so they wouldn't be high. I am using CCI primers, they are known to be harder.
Here's another picture in case it helps of the last 8 rounds from the problematic batch of reloads. Next up I'll shorten the OAL and see if that makes a difference. Of the 8 remaining/now fired, some measured as long as 1.279". [Nevermind, no new photo because there is a space limit. If I remove old photos that's not going to help others.]
