Thanks all. I took rifle apart. cleaned out the hole where the firing pin and spring goes and put in a less robust firing pin spring. The face of the bolt was indeed peened on one side. I Flitzed this out and it is smooth. I adjusted the tension spring and main spring as per your instructions. Cleaned and lubed the rest of the rifle. In the event the main spring is just plain tired. what are my alternatives if any? Tomorrow I will see if this rifle flies at the range, take it apart again and make observations and likely will report back. Skid.
