.300 Winchester Magnum Ballistics Chart

.300 Winchester Magnum drop and wind charts for a 180 grain hunting bullet, a 190 grain match bullet and a 200 grain ELD-X. All three are solved to 1000 yards under the same standard atmosphere. Every number below is solved live by the ballistic calculator on this site, not copied from a book — treat it as a reference starting point, not a substitute for truing your own rifle at distance.

Dimmed rows are below the speed of sound, where published coefficients and this point-mass model are both least reliable. The solver stops once velocity falls too low to model honestly.

How to use this chart

  • Match the zero first. These tables assume a 100 yard zero; a 200 yard zero shifts every row.
  • Match the sight height. 1.5 inches is used here; a high AR mount is closer to 2.6 inches.
  • Match the air. Standard sea-level air is thicker than most hunting country, so real drop at altitude is usually less than shown.
  • True your muzzle velocity. Box velocity comes from a test barrel — chronograph yours, then re-run it in the calculator.

.300 Winchester Magnum ballistics FAQ

How much does .300 Winchester Magnum drop at 500 yards?
.300 Winchester Magnum with the Nosler 180 gr AccuBond load (0.507 G1 BC at 2960 fps) drops 46.5 inches below the line of sight at 500 yards from a 100 yard zero in standard sea-level air, which is 8.89 MOA or 2.59 mils of elevation. It is still carrying 2089 fps and 1745 ft·lbf there.
How much does .300 Winchester Magnum drop at 1000 yards?
302.0 inches below the line of sight, or 8.39 mils / 28.84 MOA of come-up, with 1404 fps left. Time of flight is 1.48 seconds, so a switching wind matters more than the elevation by then.
How much does a 10 mph crosswind push .300 Winchester Magnum?
A full-value 10 mph wind moves it 5.8 inches at 300 yards and 17.1 inches at 500 yards — 0.95 mils. Half-value wind is roughly half that; the wind hold, not the drop, is what usually misses.
Should I dial MIL or MOA for this chart?
Whichever your scope is marked in — the two columns describe the same come-up. One mil is 3.6 inches at 100 yards and one MOA is about 1.047 inches, so mils give coarser, faster clicks and MOA gives finer ones. Never mix a mil reticle with an MOA turret.
Where does .300 Winchester Magnum go subsonic with this load?
It is still supersonic at 1000 yards under these conditions, which is why the table stays useful across its whole range.

Before you trust these numbers

Factory muzzle velocity is a starting point measured in a test barrel. Barrel length, throat, temperature and lot number all move it, and 50 fps of error is worth most of a click at distance. Confirm on paper at 300 and beyond before you hold off an animal or a plate.
