Looking at the photos of the targets you shot with the rifle, it looks to be quite acceptable for hunting purposes, even though it is a bit disappointing from the standpoint of tight groups. It is frustrating to put that much time, effort and money into a project without getting results commensurate with the investment.
I would suggest that the majority of hunters could use that rifle successfully and never notice that it isn't a barn burner.
Years ago I rebuilt a Ruger 77 .30-06, sent it back to Ruger for a reblue (when you could do such things) and refinished the stock, including recutting the checkering. It also didn't group particularly well. I ended up selling it to a chap who had tested it. It met his expectations for accuracy. He was very happy with the rifle.
