I had a simmons 8 point on one of my .22's and had no complaints about it except that the shots could vary by 1/2 inch at 50 yards by the way I held my head on the stock. For a $50 scope its plenty good for plinking and small game hunting, but I personally would put something better on a rifle for big game.
My brother in law has an older simmons on his 7400 that he uses for deer hunting that he doesn't seem to have any problems with though.
