Daren - just for the heck of it, I refined the numbers by working backwards using a CCI 40 gr Standard Vel. to figure out the ballistic coefficient which was the missing ingredient in the previous calculation. So at the same vel. as before, 1120 fps, it looks like the drop is closer to 37" at 200 +- 1". That's still in the range I originally quoted, but it should get you closer with fewer shots. If you notice that you are not getting a sonic "crack" with your ammo, add a few more inches.
