There is a good resource here => http://handloads.com/calc/index.html

Unfortunately, not metric but you should get close. It does not open correctly with Firefox but IE works. Haven't tried any other browser.

Knowing bullet diameter, weight, shape and velocity, one may set the zero to almost any distance and see the theoretical flight path. Because my closest range is only 50 yards, I use it quite a bit for initial sight in.
