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 below the line of sight. Thus between the muzzle and the distance given as the MPBR, the bullet never strays more than 3 inches above or below the line of sight (1.5 inches for varmint loads).

Suppose I have a .308 Winchester rifle that I wish to sight-in to shoot a 180 grain hunting load to a +/- 3-inch (6-inch target diameter) MPBR range. Assume that the muzzle velocity (MV) of the load, fired from my rifle, is 2540 f.p.s. and the conventional (G1) ballistic coefficient of the bullet is 0.425; also, the line of sight of my scope is ...

This calculates the maximum point blank range (MPBR) of a firearm. MPBR is the farthest distance you are able to shoot a firearm without holding over. This calculator will give you the range you should zero your rifle in order to have the largest MPBR as possible.

2014年12月27日 · How did barrel length affect Maximum Point Blank Range (MPBR)? Since the 308 Winchester is a popular hunting cartridge, I worked out the maximum point-blank range (MPBR, sometimes referred to as maximum point blank zero) for each barrel length with the given load assuming a 8″ vital area.

2020年11月12日 · MPBR is the distance over which a shooter can hold his sights dead on the center of the target and hit it. 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.)

2020年7月16日 · Zero your rifle using the Maximum Point-Blank Range (MPBR) system and you won’t need a laser rangefinder, turret dialing or Christmas tree reticles. For game from 10 to 300 yards, sometimes even 400 yards, you don’t have to touch your scope or even think about it.

2018年11月28日 · MPBR is a calculation based on a variety of factors, including rifle caliber, bullet speed, bullet weight, ballistic coefficient, and the range at which you zero your rifle. In general layman’s terms, MPBR is the maximum distance at which you can hold dead nuts on the center of big game animal’s vitals, and the bullet will not drop below ...

The 308 Winchester is popular with hunters, police, military and long range target shooters worldwide, and to get the most from this cartridge, you need to know 308 ballistics. In order to consistently hit deer-sized targets at 300 yards and beyond, or determine the best sight settings for long range target shooting, u

Briefly stated, a �six Inch maximum point blank range� allows you to aim at the center of the heart/lung area of your targeted big game animal and your bullet's trajectory does not exceed three inches high or three inches low during its flight to target.

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 below the line of sight.
