I tightened the barrel nut and then took the second piece of brass, which i put a piece of tape that measured .0040 in thickness in the chamber and tried to close the bolt. The bolt will only close about 10% in rotation. I then took a loaded shell (Nosler) and took the gun outside and the nosler ammo loads without issue. Should I still rent a no go gauge to ensure the headspace is correct or call it good?

Thanks
I use the tape method, and use 3 or 4 pairs of fired fl sized cases, no-tape and tape. To answer your question: I would try 5 or 6 of the Nosler cartridges. If they chamber without problem, I'd put 1 layer of tape on the case head and try them. Then 2 layers. If there's resistance to chambering with 1 layer-OK. If there's resistance to chambering with 2 layers, OK. If there's no resistance with 2 layers, I would start over. BTW, I take the ejector and the firing pin assy out of the bolt before any of this. That's my opinion.
