Lots of detailed info here! Saving a link to refer to later. 
Zeroing scopes will guaranteed be in the game, not sure about the Coriolis effect and Magnus effect - since they add so much extra complexity they might be confusing like “Unturned is broken the bullets sometimes don’t act predictably”. I like the idea of the realistic scope distances, might be tricky with different FoV but I think the scopes might use primitive line drawing rather than images for the reticules to make sure they’re pixel perfect.
