Today when testing my new scope my new to me 10 FP in .308 failed to extract. I took out the bolt and fiddled with the extractor which seemed to be "stuck" In the process the little "claw slipped out and I heard the dread sound of a part disappearing. I found the actual extractor, but the ball is gone. I put a #4 shot on the spring and it actually seems to work now. However, this can't be a satisfactory fix, so what to do? I see on another thread that a slightly larger ball may be a better solution than the original? What is the thinking on this?
