Also remember these tabels are approximations - you will have to to the shooting to verify. In these tables I left the elevation @ 3000 ft and the Temp @ 50* both of these can change the flight path a bit also.

13/1400 fps & 12/1300 fpe @ 200 are real nice numbers to be dealing with at that range... but then again the 275 is not that far behind....
