.300 Blackout Trajectory Calculator

See how .300 Blackout stacks up in our full caliber comparison chart — energy, drop and recoil for every rifle caliber side by side.

The .300 Blackout offers AR-15 compatibility with .30 caliber punch, though its rainbow trajectory limits effective range. With a 125-grain supersonic load at 2,185 fps and a 100-yard zero, expect about 8.2 inches of drop at 200 yards, 29.4 inches at 300 yards, and 68 inches at 400 yards. Energy drops below 555 ft-lbs by 300 yards, making it a 200-yard cartridge for deer-sized game. The .300 Blackout shines inside 150 yards, especially suppressed.

Use the calculator to match your specific load. Click "Modify Calculation" to enter your bullet weight, muzzle velocity, and ballistic coefficient. Supersonic and subsonic loads have dramatically different trajectories—subsonic 220-grain loads drop much faster but work well suppressed at close range. Factor in your specific ammunition choice for accurate holdover data.

Zeroing the .300 Blackout

Every table in this section uses the same reference load as the calculator above, 125gr G1 .272 at 2,185 fps, with a 1.5" sight height over the bore, at standard conditions (59°F, sea level, no wind for drop; 10 mph crosswind for drift). Intermediate cartridges are usually shot from a flat-top rifle with the optic well above the bore, which is why AR zeros are argued about more than any others. Change the bullet, velocity or sight height in the calculator above to solve your own load.

At this page's 1.5" sight height a 50-yard zero crosses back at 74 yards, not 200. The familiar "50/200" AR zero depends on the 2.6" optic height of a flat-top rifle.

How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 8" vital zone, ±4" either side of the line of sight. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 300 yards.

Key terms

Near zero
Where the bullet first climbs up through the line of sight. It starts below the sight, because the sight sits above the barrel.
Far zero
Where it falls back down through the line of sight. A "200-yard zero" is the far zero; the near zero comes with it.
Max ordinate
The highest the bullet gets above the line of sight, between the two crossings. This is what makes a zero shoot high in the middle.
Point blank range (MPBR)
The zero that keeps the whole arc inside a vital zone for the longest distance, so you can aim at the centre and hold dead-on.

.300 Blackout with a 50-Yard Zero

Zeroed at 50 yards with a 1.5" sight height, the 125gr load crosses the line of sight on the way up at 50 yards, peaks +0.1" at 62 yards, crosses back down at 74 yards, and is -0.6" at 100 and -9.4" at 200 yards.

Maximum Point Blank Range for the .300 Blackout

Maximum point blank range (MPBR) is the zero that keeps the bullet inside a vital zone, never more than half its height above or below the line of sight (an 8" zone is ±4"), for as far as possible. Zero at the distance in the table and you can hold dead-on from the muzzle to the far edge of the window.

.300 Blackout maximum point blank range by vital zone size
Vital zone Zero at Hold dead-on from To (MPBR) Max ordinate Near / far zero CSV
8" (whitetail, pronghorn) 197 yd 0 yd 230 yd +4.0" at 111 yd 17 / 197 yd Download
10" (elk, moose) 214 yd 0 yd 250 yd +5.0" at 119 yd 16 / 214 yd Download

MPBR assumes a centred hold, a level shot and no wind; it is a ceiling, not a licence to skip ranging. The far edge of the window is where the bullet has already fallen half the vital zone.

Which Zero Should You Use for the .300 Blackout?

The supersonic 125gr .300 Blackout has a curious property at this page's 1.5" sight height: the 36-yard zero and the 100-yard zero are the same trajectory. Both cross the line of sight at 36 or 37 yards on the way up and at 100 on the way down, peaking 0.45" high at 68. So the choice is really between that trajectory and a 50-yard zero, which crosses back at 74 yards and buys you nothing you can use.

Zero the supersonic load at 100 yards. Inside 165 yards the bullet stays within 4" of the line of sight, which covers the ranges a 16" or shorter Blackout is actually asked to shoot. Past that the arc falls away hard, 29" low at 300, and the bullet goes transonic around 470 yards. If you hunt hogs or deer with the supersonic load and want a hold-dead-on window, the MPBR zero of 197 yards keeps you inside an 8" zone to 230 yards.

The subsonic loads are the other half of this cartridge and they need their own zero. A 200-plus grain bullet leaving at about 1,050 fps drops several times faster than the 125gr load, so on a supersonic 100-yard zero it prints well low by 100 yards. Zero for whichever load you shoot most, record the offset for the other at 50 and 100 yards, and treat that offset as a second dope card rather than trying to split the difference.
