I'm new to using MPBR data. Here's what I don't understand when inputting a 200, 150, 100, 50 and 25 yard zeros into the software I get very different data readings but the 25 yards zero says I'd get the but shooting range then all the others. at my house I can set up a 25 and 50 yard ranges with just enough room but cant get any further distance without having to travel to a range. When I input all my information and a 25 yard zero it says I'd be able to shoot from 0-325 with a maximum of -8.01 inch bullet drop at 325 yards but if I put in a 200 yard zero I'd get a much higher 325 yard bullet drop is this from gravity and if so would a 25 yard zero be the best zero for my rifle. I'm retired military and the more I think about this is what we have done for years in the Army a 25 yard zero then be able to high 300 yards with ease. I've never read about it before. Another question is how would I be able to input my data for my muzzleloader to get good data as well for the gun. Thanks

You post is a little hard to read, it looks like maybe part of it got partially deleted.

The PointBlank range calculation ignores whatever value your target zero is set to. It computes several trajectories, each with a different kill zone height, in 2" increments.

So for a 6" kill zone, it computes a trajectory that is 3" high above the line of sight, then find the range where its 3" below the line of sight and returns those values along with where it crosses the line of sight (sight in range). That gives you the sight in value and maximum range before you have to adjust elevation for a longer shot.

If this is not what you are referring to then I misunderstood, and need a little more clarification.
