RE: When is it "good enough?"
Well for me accuracy is part of this hobbie we have. I am alway trying to get better groups. I have many hunting rifles grouping near 1/2" but will accept 1". I have a rem 597 set up with the same trigger pull and scope as most of my hunting rifles so I can practice shooting. A thousand rounds through it a few hundred through the hunting rifles and I fell quite confident I'm more than ready. Have you ever gone rabbit hunting with a .300 wim mag? After a few dozen rabbit a deer looks like a barn door.
