Without knowing your actual velocity and without actually shooting, it's just a guess. You can subtract 25-50fps per inch of barrel length from KNOWN velocity, but numbers published on a box aren't what your guns does. Without a chronograph, your just guessing.

To get some general ideas, use something like JBMs trajectory calculator.
