It reads to that but with is its accuracy tolerance. I have seen meters that read to levels that are beyond what its accurate to. It was rather a surprise to me when I was reading the specs on some. As Hornady got I think so many pone calls on the lots that measured large my bet is they were a bit more careful on there next run to come in at spec and tighten up the tolerance.
What I do not like about throating beyond doing it just for the one bullet is you still have more pressure as your are engraving deeper with not just the lands but now the groove diameter as well. I recall the old tight palma barrels because the sierras 155 were below standard bore groove spec.. That went on for some years too.
