It does close smoothly on the go gauge and does not even begin it let the bolt rotate on the no go gauge. Both gauges are PTG and I have used them before on another rifle. I had factory unfired rounds fail to extract on both the Nosler 140 gr Accubond and some Fiocchi 142 gr MK. I guess I do not have the tools to measure the cases. I also have not fired this rifle yet as I wanted to make sure that I would not have to worry about undue pressure due to tight headspace. Like I said I did notice after I colored a bullet (not the case) with a perma marker it was scratched after ejection. Any other ideas on what I should check?

The only resistance when running the bolt is actually at the top of the stroke. Seems like I have to push forward just a touch. The bottom of the stroke has no discernible pressure with the gauge or loaded round.
