You take a hunter that has a few bad habits and is no better than a 2 MOA shooter, put him in a treestand or anywhere besides a perfect rest, and then give him a 4 MOA rifle and do the math. Don't forget to factor in wind, nerves, low light/visibility issues and so on. Sounds to me like a toss up on whether or not he's gonna hit a deer or anything else out past 100 yards or so.
I ain't gonna have a rifle that can't shoot better than I can shoot it. If a bolt gun won't shoot inside an inch at 100 yards I don't want it. They make new ones everyday that will.
