.300 Win Mag Trajectory Calculator
See how .300 Win Mag stacks up in our full caliber comparison chart — energy, drop and recoil for every rifle caliber side by side.
The .300 Winchester Magnum is a flat-shooting powerhouse built for long-range hunting. With a 150-grain bullet at 3,260 fps and a 100-yard zero, expect about 2.4 inches of drop at 200 yards, 9.3 inches at 300 yards, and 21.6 inches at 400 yards. The cartridge retains over 1,790 ft-lbs of energy at 400 yards and 1,485 ft-lbs at 500 yards—more than enough for elk at extended range.
Use the calculator to match your specific load. Click "Modify Calculation" to enter your bullet weight, muzzle velocity, and ballistic coefficient. The .300 Win Mag spans 150-grain speedsters to 220-grain heavyweights, each with different trajectories. You can also factor in wind, shooting angle, and atmospheric conditions.
Compare up to 5 different loads. The current caliber (.300 Win Mag) is pre-selected for the first load.

Zeroing the .300 Win Mag
Every table in this section uses the same reference load as the calculator above, 150gr G1 .392 at 3,260 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). A hunting rifle with a scope in standard rings sits about 1.5" over the bore; the zero you choose sets how far you can hold on hair without thinking about the range. Change the bullet, velocity or sight height in the calculator above to solve your own load.
.300 Win Mag zero comparison
| 100-yd zero | 200-yd zero | |

| Near zero | 83 yd | 40 yd |
| Far zero | 100 yd | 200 yd |
| Max ordinate | +0.0" | +1.3" |

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 500 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.

Maximum Point Blank Range for the .300 Win Mag
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.
| Vital zone | Zero at | Hold dead-on from | To (MPBR) | Max ordinate | Near / far zero | CSV |
|---|---|---|---|---|---|---|
| 8" (whitetail, pronghorn) | 298 yd | 0 yd | 349 yd | +4.0" at 167 yd | 26 / 298 yd | Download |
| 10" (elk, moose) | 325 yd | 0 yd | 381 yd | +5.0" at 180 yd | 23 / 325 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.
