Point blank range meaning11/10/2023 ![]() ![]() A 3 inch MRT also allows for a little bit of human error, which is probably a good thing when shooting in the field. 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. ![]() Allowing a greater mid-range trajectory might result in shooting over an animal at an intermediate distance.Ī maximum rise of 3 inches is appropriate for hunting the smaller species of big game, creatures from perhaps 75 pounds to 150 pounds on the hoof, which typically have a kill zone of about 8 inches from top to bottom. In the table below I used the term "mid-range trajectory," abbreviated "MRT."Ī maximum bullet rise of 1.5 inches is appropriate for shooting small animals, as they present a small target, particularly if head shots are necessary. In ballistics catalogs the point of maximum bullet rise is often called the mid-range trajectory, or sometimes the maximum ordinate. 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. (It may well vary.) This trajectory table can also serve as a comparative tool, allowing the reader to compare the trajectories of different cartridges or loads. So after sighting-in, always check your individual rifle at various ranges to see how close its trajectory comes to the published data. Of course, no trajectory table can possibly cover all loads for all calibers in all rifles. Used as such it can save a lot of trial and error experimentation. The table below is designed to serve as a starting point from which a shooter can work. Of course, the actual distance the bullet should hit above the point of aim at 100 yards (or 100 meters, which is about 108 yards) varies with the individual caliber and load. This system maximizes the distance in which no "hold over" is necessary. 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. In order to hit a distant target a rifle must be correctly sighted-in, and to accomplish that the shooter must have some working knowledge of the bullet's trajectory. ![]()
