.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.
