I'm back with an update.
Installed the Wolf #17 hammer spring for a range test.
Every round fired and not one 32 SWL primer pierced out of forty fired.
Twenty two rounds of full power loads fired
with zero pierced primers.
Twenty eight rounds of mid range loads fired with five pierced primers.
There were no other failures or jamming of the cylinder caused by the FP spot welding to the primer.
It seems my seven year quest to have a SS function properly is almost achieved.
I will polish down the FP a bit to try to eliminate the mid range load issue.
Just need to shoot some more ammo to see if the misfire problem will return when the FP bushing gets a bit dirty.
Thank you all for listening.
