Primer pocket uniforming question

[Catfish]

I have never found doing the primer pockets to get me more than .010 smaller groups. In bench rest shooting this can mean the difference between winning and loseing, but but with a hunting rifle you`ll never be able to tell the increase in accuracy, and this would also hold true for alot of varment rifles. I have seen flash holes that were off center, but they are very rare and you through those out.
