CEA Headshot glitch

So ive noticed whenever im playing CEA, in order to get headshots i have to shoot slightly above the enemies head, is this bullet drop? or is it a glitch

I don’t have that problem, is it still the same when you go back to classic mode?

you do have to lead your shots much like the br in halo 3 in case you didn’t know if this is the case

The issue is only with the Magnum

Try shooting at an enemy’s head without scoping in and without turning the crosshair red.
