Frank, I don’t know didley about that- thus, I can’t offer a solution. But I sent you the name of someone in your area that can help you determine whether it’s a problem with the gun or not. Check your ‘conversations’. Rudolph raises a common problem with some combination of reloading components. Best
Frank, please let us know the results of the diagnosis on the stiffness, as now I think about it mine is sometimes reluctant to open. Haven't noticed if it's on 2nd shots or not (having way to much fun) but am interested none the less. Cheers B.
