Confused over Berger seating depth test

[Jeff Porter]

Fwiw…. I am currently shooting Berger 80.5’s in my service rifle jumping them 0.130” after similar results in a jump test. Other barrels shot better jumping 0.040”

This is a screen shot of the 80.5’s at 600 with a 4.5x scope with that jump.

Here is a set of 6BRA with 108 Bt Berger’s fireforming. All were very good. One was better. That’s what I use.

I know with VLD you better test seating and nail it or else you’ll be scratching your head trying to get the load to shoot well.

I’m using Berger 90BT . Went out today and started test at .01 into the lands and load shot so well at 300 yards I never adjusted seating depth .
