How far can a 17hmr shoot?

The maximum range is somewhere around 1.5 to 2 miles, however, it's effective range is much less. These are extremely accurate cartridges to about 125-150 yards. Beyond that, the round is dropping velocity quickly due to the very light weight bullet, and at 200 yards would be 5 inches below the line of sight for a 100 yd zero, and drop even more quickly beyond 200.
