5.56 NATO Ballistics Chart
5.56 NATO drop and wind charts for M193, M855 and 77 grain OTM class loads at service-rifle velocities. Same bullets as .223 Remington in places, but a different pressure and barrel standard. 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.
Standard conditions used for every chart on this page
- Zero
- 100 yd
- Sight height
- 1.5 in over bore
- Atmosphere
- 59 °F, 29.92 inHg, 50% RH, 0 ft (ICAO standard)
- Wind
- 10 mph at 90° (90° = full-value crosswind from the right)
- Shooting angle
- 0°
- Spin drift / Coriolis
- Off — not modelled by this solver
- 5.56 NATO is loaded to a higher pressure in a longer-throated chamber than .223 Remington. 5.56 ammunition should not be fired in a .223-only chamber; .223 ammunition is safe in a 5.56 chamber but usually slower.
- Velocities here are 20 inch rifle figures. A 14.5 or 16 inch barrel typically loses 100–200 fps, which moves the 500 and 600 yard rows noticeably.

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.
5.56 NATO ballistics FAQ
- How much does 5.56 NATO drop at 500 yards?
- 5.56 NATO with the Federal / Lake City 55 gr M193 load (0.243 G1 BC at 3165 fps) drops 58.8 inches below the line of sight at 500 yards from a 100 yard zero in standard sea-level air, which is 11.24 MOA or 3.27 mils of elevation. It is still carrying 1475 fps and 266 ft·lbf there.
- How much does 5.56 NATO drop at 1000 yards?
- The table here stops at 600 yards for this load, because the solver will not report a trajectory once velocity falls below the range where this model is trustworthy. Use the shorter distances and confirm the rest with live fire.
- How much does a 10 mph crosswind push 5.56 NATO?
- A full-value 10 mph wind moves it 12.2 inches at 300 yards and 39.6 inches at 500 yards — 2.20 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 5.56 NATO go subsonic with this load?
- It is still supersonic at 600 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.
