I have to qualify at an outdoor range and to do so, I need to make 50 meter, 100 meter, and 200 meter shots putting lead on paper 18x24. I'm shooting my an AR with .223 and my 9mm Springfield XDm. I've done most of my shooting at indoor ranges (about 50 ft) and some USPSA shooting but rarely at this distance. I'm,not overly concerned witht the 50 meter range but what kind of (if any) sighting changes should I make at the other ranges shooting a 9mm handgun? Sounds stupid but I only get ten shots with each gun and need to hit 5 out of ten. Really don't feel like having to make the trip again to get qualified.
