One description of the MPBR concept that has been used a lot over the years is to visualize shooting with your barrel centered inside an imaginary pipe. The point blank zero would be setting in which the bullet impacts no more than four inches above or below the center of the vital zone. Allowing a greater mid-range trajectory might result in shooting over an animal at an intermediate distance. Sighting-in a hunting rifle to hit a certain number of inches high at 100 yards (or 100 meters) maximizes the point blank range of the rifle and cartridge and is superior to zeroing at a fixed distance like 200 yards.

The following data was taken from various sources including reloading manuals and the online Ballistics Calculator provided by BigGameInfo. ShootersCalculator.com is in the process of being massively overhauled. The maximum point blank zero here is 259 yards meaning you should be able to hit a 4-inch disk from 0-259 yards with a dead-center hold. By Jim Carmichel.

MPBR is the distance over which a shooter can hold his sights dead on the center of the target and hit it. The 7.62x39mm has a known ballistic coeficient of between .225 (a 123 gr bullet) and .325 (a 150 grain bullet), a very large range in deed. The distance from the muzzle, point blank, to the maximum distance before the bullet falls below vital zone threshold is the Maximum Point Blank Range. Maximum Point Blank Range (MPBR) is simply the farthest end of that distance. Ballistic Trajectory | Bullet Kinetic Energy | Point Blank Range | Recoil. Range at Max. While environmental factors such as altitude and ambient air temperature affect trajectory, their effect is relatively minor. The trajectories in the table below were calculated for a maximum bullet rise of 1.5 inches above the line of sight for all small game and varmint loads, and three inches above the line of sight for all big game loads. By crossbow standards (crossbows are notoriously loud compared to compound bows), my Ten Point is very quiet right out of the box.
