I guess on some of my cheaper guns I expect to get at least 3" or less group at 100 yards or the gun ain't worth shooting( for me anyway) On my top of the line guns I expect to get 1" groups at 100 yards and 2" groups at 200 yards. Maybe I am wrong but I figure if I pay more( sometimes a lot more) for a quality gun then it should perform better. As long as i do my part by spending the time and effort working up a load for it that is..
For me ,the principle is, If I give more for something it should give more in return.
