Primer Seat Depth, Consistency and ES

Wanted to see from the forum if anyone has done any testing with your hunting load.

1) Has anyone taken their brass and measured primer pocket depths for consistency?

2) Have you then seated your primers exactly 3 to 4 thousands deeper than the case? Or have found a node measured by depth that produced really low ES?

3) Have you seen a drastic reduction in ES when doing the above.

As some of you have already guessed and discussed with me I'm upgrading the reloading bench and getting some more education from my PRS/Benchrest brothers. I'm really impressed with the attention to detail and their ability to produce alot of rounds that are very consistent.
