The headspace on my chamber is minimum with my bolt that measures .135 deep and I polished the bolt face and lapped the lugs.
Maybe since your depth is .130 you might have too tight headspace.
The face of your bolt looks to have a lot of copper build up for 26 rounds fired.
You should have at least 4 thou headspace clearance on a new barrel and bolt.
I wouldn't use that bolt anymore until the depth can measure .135 deep.
The lugs have to be right also.
