Re: how many clicks do l go up?
Is it 5 inches or 5 MOA?
If it's 5 inches then:
An inch is 2.54 cm at 100 yards. So if you need to go up 5 inches then 5 X 2.5 = 12.5. But at 400 yards each click is 4 cm then 12/4 = 3 then you would go up about 3 clicks.
If it's 5 MOA then:
5 MOA at 400 yards = 20 inches.
20 X 2.5 = 50 cm
50 / 4 = 12.5 because at 400 yards 1 click = 4 cm.
Then go up 12 - 13 clicks for 400 yard zero.
If your trajectory does not match, maybe the speed you input is not correct. If your actual bullets speed is lower than what you are using then the bullet will strike lower than predicted. Also the BC of the bullet might be off a little.
Hope that helps.
