Re: firing pin too short
The older Savage firing pins had a step on them. The FP hole on the newer ones is the small diameter all the way back. Take everything apart and stick the FP into the bolt head and see if it protrudes out the front. I am guessing the larger part of the FP is stopping it from going all the way through. You can either turn the FP down, order a new one, or drill the hole larger to accommodate the step. If this is your problem.
