PUBG will not go higher than 103.
Your ADS and scope conversion setup should be set to MDH 0% as it will be closest to your preference, 360 distance should only be used in special cases.
You can either do like this to match your hipfire using 360 distance, and all the scopes using MDH 0%:
Or like this to match everything to 1X in BF3:
Alternatively 360 distance from the first and scopes from the second.
You can't list the sensitivity in the PUBG config file in a nice matter unfortunately, but you can use the In-game calculation and enter the sensitivity with high precision there as long as you follow the instructions (i.e. don't press enter after the number is entered).
