I like this kind of shooting, it can be disheartening at time but when hunting season rolls around it pays of!
We spend all summer visiting our elk hunting areas, drive a couple hundred miles for only one shot a piece but you learn more in less time. Last year my buddy went 6 weekends straight cold bore on our plate at 1030 and you could cover the group with your hand, first shot of the hunting season he put his first round within a couple inches of his aim point on an antelope at over 900 yards, cold bore practice paid off for both shooter and spotter!!!
