After thinking on it a while, I wonder of one possible solution to spring woes might be to have someone like Wolff run us a group buy on higher grade springs than NEF is using. The hammer spring on my 38-55 got weak enough that after 2500-3000 rounds (cycles) it would no longer drive the hammer with enough force to reliably ignite rifle primers. I wonder too if a stronger firing pin spring could prevent firing pin breakage and if a stronger return spring for the lock would help create a more consistant lockup. Thoughts???
