You need to read everything I have said about hammer springs and primer impact.
Randy has the answer. Even all of my revolvers get an over power springs before shot.
I get nothing but flack over this with guys changing to lighter springs or backing out strain screws.
Refreshing to hear experts chime in after I get bashed over and over.
The junk of changing the primer is so much bull because even federal primers need impact. When is primer cup thickness going away?
Oh yes, a weak hammer fall will turn a gun into a shot gun. You are smart to listen. Just making a primer pop is just not enough. I learned in my IHMSA days when Rugers shot worse and worse. I bought springs by the dozen because they took a set. A spring change brought back accuracy but the Wolfe over power springs last longer.
