Inconsistent Firing Pin Strikes?

[HandgunHTR]

I wonder what trigger Proof uses on that gun. Based on the pic of the bolt head, you can see that there is obviously more contact on the top of the bolt face than the bottom.
My thought is that when the sear is engaged it is putting upward pressure on the bolt, causing the rear of the bolt to lift and therefore not have good contact with the case And allowing for off-center primer hits.
I have seen this before with Remington and Mauser actions that had bolt races that were a little oversized.

Floating bolt head
bolt/raceway clearance
small brass
fat chamber
headspace
Could be any one or more likely a stacking of clearances but not necessarily a problem. How’s it shoot?

It didn't shoot quite as good as I hoped. I did get a 5-shot 1" group with 145 eldx superformance. The norma 130 soft point ammo I bought for practice shot about 1.5 as did Hornady Superformance 130 gmx.

The trigger is: Trigger Tech Primary

I don't mind sending it back on their dime, this time of year.

What’s the verdict?

I'm thinking it's ejector related. It'll be interesting to hear what the outcome is.
