So, a question some of you may be thinking: "why practice at shorter ranges? Why not practice at actual distance?"
Those are some good questions for which there are many answers. In some locations, we don't have the luxury of distance. If we can find a spot that goes out to a couple or 300 yards and has an adequate backstop, we are very lucky. Another reason is we may not always have access to the actual ranges. Range time is often booked in advance with members having priority. Given I am a member of one club, I have priority but no longer the luxury of proximity.
Therefore, this "spot" we have is perfect.
Also, by practicing on the reduced targets, what I am really focusing on is the hold. Case in point, the diameter of the X-ring on the MR-1 target is 6 inches. For the MR-63 it is 2.85 inches. If I wobble even as much as a quarter inch at the firing line, that translates into as much as 3/4 inches at 300 yards. Add in the effect of a typical 1 MOA cross wind, that is now 3 additional inches of error. And now into the 9 ring. So hold and ability to read the wind are equally important. If a shooter can master that, then distance becomes irrelevant as longs as they know the dope for their rifle and ammo.
