To get maximum horizontal range the gun should be fired at a 45 degree angle, it won't give you maximum time of flight (that would be 90 degrees) or maximum horizontal speed (that would be 0 degrees parallel to the ground) but it would be the best compromise between the two factors to get the most range. </font></div><div class="gmail_default"><font size="4"><br></font></div><div class="gmail_default"><font size="4"> John K Clark </font></div></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><br>
