No.4 T shooting at 400 yards.

I am guessing you haven’t zeroed your scope dims to bdu marking. Assuming your ammo is similar to mk7 the following should be true. 100-400 should be 12 clicks. However if you are shooting something like PPU 174 fmj that is quite hot and a bt, when I was shooting this 100-500 yrd I typically set 50 yrds under so if that was the case you would only be adding 10 clicks.

0-100 = 3
100 -200 = 4
200 - 300 = 4
300 - 400 = 4
400 - 500 = 4
500 - 600 = 6
600 -700 = 7
700 -800 = 8
800 - 900 = 9
900 - 1000 = 11
