try
mouse_sensitivity "2.005262"
mouse_zoomed_sensitivity_scalar_0 "1.251484"
this is with 360 distance on the ads conversion - it's what i use and it feels fine for me - just added your 360 distance from your destiny 2 cm/360
this is the base fov, you'll have to find out and convert destiny's 105 fov to apex, destiny had quite a low fov even when maxed out though, so i assume it's 90ish - the fov only matters when you ADS though.
Other calculations I've seen are like this:
1x = 1.25 (round about here with extra numbers to fine tune)
ADS = 1.4
Always set to 1x, as this is the majority of the scopes.
