Petrov Posted June 29, 2020 Share Posted June 29, 2020 Om having rough indexing and sideways primer issue with my SDB. Took my shell plate off and found this. That is a very deep groove worn where the index bolt sits. Bottom of the holes where the primer cup goes looks damaged too. Link to comment Share on other sites More sharing options...

lonestardiver Posted June 29, 2020 Share Posted June 29, 2020 Check with Dillon. They may replace it. Link to comment Share on other sites More sharing options...
Petrov Posted June 29, 2020 Author Share Posted June 29, 2020 (edited) Called dillon they said it should not affect the function but offered to send a new one out. I already ordered one so i declined. I checked my primer slide cup/pin/spring assembly and it was too long, the set screw was basically loose, made it proper length. I am now trying to sort out the plate popping/jumping at the last 1/4 of upstroke. It looks like the metal arm that pushes on the metal shell plate pushes inside the plate instead of pushing it out and it seems that is where the snag and sudden jump in my plate happens. pic: Edited June 29, 2020 by Petrov Link to comment Share on other sites More sharing options...
