.300 Winchester Magnum Ballistics Chart

.300 Winchester Magnum, 180 grains, leaving the muzzle at 2,960 feet per second and zeroed at 100 yards, lands 11.7 inches low at 300 yards and 49.1 inches low at 500, with 1,546 foot-pounds still on it at 500. That is the short answer; the full .300 Win Mag ballistics chart is below, and every load on it opens in the calculator with its figures already in.

The .300 Win Mag ballistics chart: how far each load drops

Standard sea-level day, 100-yard zero, scope 1.5 inches above the bore, 10 mph crosswind from three o’clock. Drop is measured against the line of sight, so a negative number is below your aiming point. Every muzzle velocity and ballistic coefficient is the figure the maker publishes for that catalog number.

Run your own rifle

Every load above opens in the ballistic calculator with its figures already filled in. Change the muzzle velocity to whatever your chronograph actually says, set your zero, and drop, energy, wind, recoil and scope clicks all update together.

How this .300 Win Mag ballistics chart was worked out

A point-mass solver stepping half a thousandth of a second at a time, using the G1 standard drag function — the published table of drag against speed that the ballistic coefficients on the box are measured against. Air is the ICAO standard sea-level day: 59 °F, 29.92 inches of mercury, dry. Crosswind uses the lag-time method. The full method, the formulas and a worked example you can check on paper are on the ballistic calculator page.

The check that matters: the muzzle-energy column above is computed, not copied, and it lands on the same figure the maker prints for every load on this page. If it did not, nothing here would be worth reading.

Questions and answers

How much does .300 Win Mag drop at 500 yards?

About 49 inches below the line of sight from a 100-yard zero, for the 180-grain load at 2,960 fps. Across every load on this page the spread at 500 yards is 1.1 inches, so the load you pick matters less than the zero you pick.

What is the best zero for .300 Win Mag?

Two hundred yards suits most hunting. It keeps the bullet within a few inches of the line of sight from the muzzle out past 250 yards, so there is nothing to think about on a close shot. A hundred yards is the better choice if you dial your turret for everything past that, because the come-ups are simpler to read. Set the zero field in the calculator to either and compare.

Does barrel length change these numbers?

It changes the only number that really matters. These velocities come from the maker’s test barrel, usually 24 inches. A 22-inch barrel typically gives up 25 to 50 fps, and a 20-inch barrel more than that. Chronograph yours and type the real figure in.

Why does the heaviest bullet not always drop the most?

Because drop follows time of flight, and time of flight follows how well the bullet holds its speed — which is ballistic coefficient, not weight. A heavy bullet that starts slower can still catch up by 500 yards if its coefficient is high enough. The wind table above shows the same effect more starkly.
