@mtmojo I signed up here just so I could post a thank you for this thread. This was the ticket to fixing a pretty frustrating issue with my Redline 2020.
Only had about 65 rounds thru mine when light strikes started happening while working up a hand load. I was on a path to replace the striker spring when I finally stumbled on this thread. I actually may have over corrected screwing the firing pin in as far as possible. The primers were looking pretty severely dented so backed off a little. But back to 100% again. Thanks man!
