[QUOTE="J E Custom, post: 1417202, member: 2736"] When Head spacing a cartridge, I always remove the firing pin assembly because the firing pin spring is loading the bolt and will give you a false reading/feeling. I also always remove the ejector plunger because it also pushes on the case head and can also give you a false reading. The only thing I leave on the bolt body is the extractor and I use it to hold the go gauge for insertion into the chamber. With the bolt stripped. This way the readings are very accurate and repeatable because there are no external or internal forces to alter the readings. So if you removed the firing pin assembly, the slight resistance you felt was probably from the ejector plunger if using the go gauge. if your brass is not sized correctly for your chamber, then this could be the issue when using brass with or without the firing pin assembly or the ejector plunger.
