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. Allowing a greater mid-range trajectory might result in shooting over an animal at an intermediate distance. In ballistics catalogs the point of maximum bullet rise is often called the mid-range trajectory, or sometimes the maximum ordinate. Point Blank Range is the range you can shoot line-of-site and hit a target of a given size. All objects at the same geographic location fall with the same acceleration , denoted g , roughly 9.8 m/s² (32 ft/s²). What is the maximum point blank range for your load.

Maximum Point Blank Range (MPBR) is simply the farthest end of that distance. All trajectories were calculated for a rifle with a low mounted telescopic sight of moderate size whose line of sight is 1.5 inches above the bore axis of the barrel. More mid-range rise can be accepted when hunting larger animals (a 4 inch MRT might be appropriate when hunting mule deer, for example), but if a mixed bag hunt for larger and smaller species is envisioned, then the 3 inch rise used for this table is probably safer. 460 m, or 500 yards. To learn how to do it on the cheap, use a 22LR and keep your maximum range less the 100 yards. That means that if you aim at the center of the vital zone of a deer at any range between 0 and 300 yards, you will hit the vital zone. In order to calculate this you need to input the size of your target. Open Country. (From The Personal Range Limit.) This makes the .22 WMR an effective short to medium range varmint rifle cartridge. MPBR works with any rifle, cartridge and bullet, but the faster and more efficient the bullet, the farther MPBR extends. This is wonderfully liberating.

The Maximum Point Blank Range (MPBR), which is shown in the last column of the table below, is the distance at which the bullet falls 3 inches belowthe line of sight. To save space, the following abbreviations are used in the table below: Wb = Weight of bullet (in grains); MV = Muzzle Velocity (in feet per second); BC = Ballistic Coefficient; MRT = Mid-Range Trajectory; yards = yds. MPBR is the farthest distance you are able to shoot a firearm without holding over.
