Solved at standard sea-level atmosphere (59°F, 29.92 inHg) with a 100 yard zero, 1.75" sight height and a 10 mph full-value crosswind. Drop is relative to your zero.

Quick answer

With a 100 yd zero, a 250 gr match .338 Lapua Magnum load (250 gr, 2950 fps) drops 10.3" at 300 yd, 42.8" at 500 yd and 262.9" at 1000 yd. Change the load or zero above to see your own numbers.

The .338 Lapua Magnum chart barely bends where others fall off a cliff: 250–300 grain bullets that hold supersonic past a mile and carry rifle-cartridge energy the whole way.

At these BCs and velocities, atmosphere becomes the dominant error source — solve for your actual density altitude, not the standard-atmosphere numbers below.

Frequently asked questions

With a 250 gr match load at 2950 fps and a 100 yard zero, a .338 Lapua Magnum drops about 42.8 inches at 500 yards (8.2 MOA / 2.4 MRAD), and about 10.3 inches at 300 yards. The full chart above covers every range and load.

A typical 250 gr match load leaves the muzzle at 2950 fps with 4832 ft-lbs of energy. At 500 yards it is still moving 2241 fps and carrying 2789 ft-lbs. These figures are solved from the load data, not copied from a box chart.

A steady 10 mph full-value crosswind pushes the 250 gr match load about -13.2 inches at 500 yards. Wind drift grows faster than drop with distance, which is why wind reading matters more than memorizing holdover.

This 250 gr match load stays supersonic to at least 1000 yards under standard conditions. Accuracy degrades through the transonic band (roughly 1,340 fps), so treat that as the practical ceiling for predictable precision. Terminal effectiveness on game depends on the energy column above — most hunters watch for 1,000 ft-lbs on deer-class animals.

Your barrel length, actual muzzle velocity, and the day’s density altitude all shift the solution. These tables use standard sea-level atmosphere and published velocities. Chronograph your load, solve for your real conditions, and true the result against actual impacts — the Atlas Ballistics app does all three.
