How do you find your maxium point blank range? data?

You first decide what your kill zone diameter is. For argument's sake let's assume 6" is the kill zone. Your point blank range is the range at which your bullet strikes 3" below your point of aim when your rifle is sighted such that the bullet will be at a maximum of 3" high somewhere along the way to the target. Put another way, if you had a 6" diameter pipe you were shooting through, the bullet would just kiss the top of the pipe on it's way and would strike the bottom of the pipe at your max point blank range. Same for and 8" kill zone, except you would now sight the rifle in to be no more than 4" high at some point and the PBR would be when it reached 4" low.

You can go into the charts in the back of the reloading manuals and try to sort through the trajectories until you find yours. It might be a bit of a headache but you can figure it out this way.

An easier way is to download the free ballistics program that is floating around the internet. Conveniently, it's called pointblank. Here's the link to the page where you can download it: http://www.huntingnut.com/pointblank.html

It's very good software, and as mentioned before it's free. Just download it and start typing in your numbers for your load. It gives you all kinds of trajectory, velocity, and energy data. It also has a spot where you can enter kill zone diameter and it'll spit out the max point blank range of that load. Using that you can figure out how high to set your groups at 100 yds to get the max PBR out of your rifle.
