I was on vacation last week at my in laws. They have a nice 200yd backstop on one of their fields. I took my 16" AR-15 with me to give it a shot. A little background, I've never shot at anything over 25 yards away. I got a 4-12x Redfield scope for the occasion (thanks Dan!) and sighted it in at 50 yards. I then moved up the hill and used a bench to shoot from. After a little tweaking with some match ammo I was able to keep 20 rounds on an 8" target (barely). I was expecting a lot better accuracy. Am I skill or gun limited at that range?
