a rocket engine, to make a projectile rise above its initial line of launch.)īecause we can intentionally angle a barrel to throw its bullet above LOS, it is possible to select just how far above that line we wish the projectile to travel. In reality it was merely aimed at that slight, upward angle. When shooters learn that their bullets strike higher than they are aiming at 100 yards, then fall onto the POA at roughly 240 yards, they assume the bullet climbed after leaving the muzzle. That’s a myth that developed from a misunderstanding. This does not mean that bullets rise after they leave a barrel. You look at home plate, but throw the ball high in order to compensate for gravity pulling it down.īecause bullets depart much faster than baseballs and resist air drag much better, they don’t need to be angled nearly so drastically high as a baseball in order to shoot “flat” to 200 or 300 yards. This is much like throwing a baseball from center field to home plate. The bullet then departs at an angle that puts it through and above the line-of-sight (LOS), at about 30 yards for most big game cartridges. In order to make it shoot above point of aim (POA) at 100 yards, the sights are aligned so that the barrel tilts slightly upward. Here’s how MPBR works: Every bullet fired - from any rifle - begins to be pulled to earth by gravity as soon as it leaves the barrel. Aim dead-center on your buck or bull and hit it in the vitals even if its 400 yards away! How easy, how cool would that be? No dialing. The bullet may strike the upper or lower edge or any point in between, but it will not miss (unless the shooter flinches or pulls the barrel off target.) To the surprise of many, with the right cartridge, bullet and target, this “dead-on hold” can stretch past 400 yards. MPBR is the distance over which a shooter can hold his sights dead on the center of the target and hit it. Maximum Point Blank Range, however, has been. ![]() “The victim was shot at point blank range.”So what is this magical PBR? Ten feet? Twenty? The muzzle touching the victim? No one knows because the term “point blank range” has never been precisely defined. MPBR DefinedĪnyone familiar with crime movies, books or news reports knows that shooting anything at point blank range means you can’t miss. ![]() From 1 yard to as far as 300, perhaps even 400 yards, you’ll hit the vitals. Just aim at the center of the animal’s vital zone and concentrate on a clean trigger break. MPBR is a simple system, one that requires no confusing arrays, no mathematical calculations, no dialing, no stress.
