While dry firing I notice the bolt jumps upward. As well as the bolt jumping my crosshairs on only some dry fires jump as well (probably a form issue) ..are both these corillated together with the firing pin? Or what? I have search for others on this issue and found some say its big deal others say its normal, and I can't tell you If the bolt jumps when a live round is fired. I just want to know if any accuracy is effect by the bolt jump. Gun is remington sendero 300rum with a Jewell trigger.
