As close as I can figure using .161 as a BC and 1600 fps as speed at muzzle. If you are sighted dead on at 100 yards, at 50 yards youwould be approximately 1.4" high with 1412 fps and 1085 energy. At 100 yards you are dead on with 854 energy. At 150 yards you are -7" low and dropped in speed to 1128 with an energy of 692. At 200 yards, you are now -20.8" low and the energy has dropped to 586.

Your shot placement is more critical then anything else. If you can punch a hole in the right spot you should be all right out to 150 yards...
