This is what you are basically doing with putting in a heaver spring. Trying to gain lock time on a Savage action is a waste of time, as the Savage action has one of the fastest lock time out of all the actions made.
You never mention how much firing pin travel you have and this is the most important thing. Your firing pin protrusion is too much, and you are loosing travel because of it. Firing pin travel needs to be at 35 thousands to 40 thousands max. Do your self a favor and put the factory spring back in, and set the firing pin protrusion to the above.
After that if your still having ignition problems, you need to send the gun off to a Gunsmith that understands timing. The problem could be caused by the shape of the firing pin tip, (Caused by blanking primers, and other things.) you could have a problem with short travel of the firing pin, the bolt de-cocking as it is closing.
Did you make any other modifications to the gun? Such as change out the trigger, ETC. Did you fire the gun prior to changing out the spring? Did you have problems before changing parts?
