Excessive Headspace?

[SparkyLB]

Need some advice, all. I put an E.R. Shaw 270 Win barrel on my old 116. Using the go/no-go gauges to where the bolt closed on the former, but not on the latter; I found that the bolt would not close on any rounds of a box of Hornady American Whitetail 130 grain ammunition. So I re-headspaced it, this time progressively unscrewing the barrel (lengthening headspace) until the no-go gauge just barely didn't allow the bolt to close. Specifically, the no-go gauge allowed the bolt to close approximately 1/4 of a turn. From the reading I've done on this site and others, this was acceptable.

I shot my box of 20 today, and I'm very pleased with the accuracy. Once I find a bullet, powder, and the bullet jump that this rifle likes, I expect sub MOA results. The group shown is 1.09".

My question is, are these primers showing excessive headspace? I see they're somewhat flattened, but just don't know if they're a red flag. Shortening the headspace by a thou or two would be an easy job, so I'm ready if necessary.


Thanks, all.

E.T.A.
I looked at the pics and notice that in one shot there appears to be a ring around a primer, that looks like cratering or discoloration. This is not the case, it's just the picture. There is no cratering on any of the primers.
