Anyone ever had pressure issues due to a stiffer firing pin spring?

I put a wolff spring in my sav 111 7mm and ever since i have had real pressure issues with loads i did not before. Any input would be appreciated. Looking at just putting the factory back in.

No, but interested in the answer.
Will stay tuned.

Nothing eh? Maybe Im just a glutton for punishment.

What are the pressure issues?
Why did you change springs?

 

[Elkhunter1983]

Blowing primers out of loads that never showed pressure issues before, ejector marks on loads that are very much middle of the road loads. I changed it because of the jump from the old spring, it looked like an s on the firing pin. Its a good pin with a smooth trigger break now but just wondering why it would cause it. It is the only thing I have changed since these issues started.

Thanks for the patient answers.
What's the cartridge & load?
What's the head space setting?
Are the pockets tight?

I know that primer striking can hugely affect tune. I don't yet understand WHY.
Your condition here, going beyond tune, may lead to better understanding.

Mike, I agree that changing a striker assembly can mess up your tune. I always thought that it was from increased vibration from a harder strike, changing bbl harmonics a bit. ---- RHB
