I know this is an older post, but here's a fairly simple calculator to look at the MPBR on paper, and then you can switch over to the Ballistic Trajectory side and see that curve graphically, along with a table for specified distances. I use this one more than any other.

As a tip, get out a ruler and actually measure your height above bore line, that makes a big impact on the calculations.
Another piece of advice is to use the different parts of your reticle for different distances. Modern reticles have better capability for this, but even the old duplex reticles can help if you know where the "thick part to thin part" used as a point of aim will hit for you.
Next time you are at the range shooting a good group, take a shot by putting the lower part of the vertical crosshair, the point where your crosshair changes thickness, put that over your group and take a shot. It'll print high, and you can measure that and use that in your ballistic calculations. It sure beats guessing where a 16" holdover should be for where your desired impact area on the deer is.
