A gunsmith friend and I installed a new barrel on a Savage 110 today. He insisted on removing the ejector from the bolt face before setting the headspace gauge. Is this really necessary? We did not use a no-go gauge. He did test fire the gun with a factory load and the spent case did not show any sign of excess headspace, but extraction was difficult and the case looked like the neck was to long for the chamber. I would like to order a no-go gauge and recheck the headspace before proceeding further, but would like to know if it is necessary to remove the ejector. Replacing it was a pain in the back side.
