well you could always set you a target up at 2 ,,the graduate to 10 .. where ever you hit the target holding at 40 degees ,,gives you your answer..
of course you know im just kidding..
about the only reason i could use this type info would be if i thought i might be shooting into populated area several miles away.. i can tell you a 06 rnd goes a lot further than a couple o miles.. the sniper sites might have more actual info on total range ballistics.. good luck slim...
