AR-15 zeroed at 300 yards bullet drop at 200, and 100 yards

[pat701]

I have a Rock River N/M that i have taken much time to zero with M855 556 ammo at 300 yards (8" to 10" groups). I shoot it with the carry handle iron sights. I have no 300 yard ranges close to home. My question is without adjusting my sights to shoot at 200 and 100 yards how much will the bullet drop or raise at 100 and 200yards keeping my 300 yard zero? I will use Kentucky windage to make my adjustments at the shorter ranges to keep my zero. :confused:

I am not smart enough to use anything other than a 50-200yd zero. No more than 2" high or low from point blank to 250yds. Too much to remember with the 300yd zero. If I remember correctly you have to cover 6-8 inches at 175-200 with the 300. GH
