I am sure the OP is quite impressed with peoples degrees and intelects and understanding of statitics and big ole brains, but telling him about it in his reloading thread is probably more like wasting his time than actually helping him.
I would agree that the load is good enough to hunt and have fun with. And I would agree that shooting more from feild postions helps more in the field than shrinking group sizes from 1 moa to 1/2 moa from the bench would.
I think learning the process is important, and I think that's what the OP asked about and wants to learn about.
