As the BC will be dropping.

I've been also testing real world bullet drop now after finding out the hard way.

Yes it does, no option to enter the distance though, just velocity, i assume you would have to true up the data for a given distance, then look at the drop chart to get the velocity for that distance?

Some ammo makers will have the different BC values for their .22 ammo for the velocity.
Yeah, its a pain without knowing.
Hence I now always do a real world drop check.
