.300 Weatherby Magnum Trajectory Calculator

The .300 Weatherby Magnum is a flat-shooting powerhouse that's earned its reputation among serious hunters and long-range shooters. With a 180-grain bullet leaving the muzzle at 3,100 feet per second, this cartridge delivers impressive downrange performance that'll handle everything from whitetails to elk at extended distances. The trajectory chart and data table below show you what to expect when you're zeroed at 100 yards with a 1.5-inch sight height.

Every rifle and load combination shoots a little differently, so the default settings here are just a starting point. Your handloads or preferred factory ammunition might have different velocities, and your scope height could vary from the standard 1.5 inches. That's where the "Modify Calculation" button comes in handy. You can plug in your actual muzzle velocity, bullet weight, and ballistic coefficient to get trajectory data that matches your specific setup.

The calculator also lets you factor in real-world conditions that affect bullet flight. Wind speed and direction can push your shots off target, especially at longer ranges, so you can enter those values along with any uphill or downhill shooting angles. For the most precise calculations, you can also input atmospheric conditions like altitude, barometric pressure, temperature, and humidity. These variables might seem minor, but they add up when you're trying to make that perfect shot at 400 yards.
