Load'EmFree tool
Ballistics calculator
Drop, wind drift, retained velocity, energy and time of flight, using the same trajectory maths that runs inside Load'Em. Nothing to install and no account.

How to read this
Drop is measured against your line of sight, so it is zero at your zero distance and negative before it, where the bullet is still climbing to the line. MOA is the same drop expressed as an angle, which is what you dial. Wind assumes a steady crosswind at the angle you set. 90° is full value, 45° is roughly 0.7 of it.
G1 or G7?
Use whichever matches the number on the box. Most manufacturers publish G1, which suits flat-base and shorter bullets. G7 fits modern boat-tail match bullets far better and stays truer at distance. The two are not interchangeable: a G7 BC is roughly half its G1 equivalent, so putting a G1 number in a G7 calculation will be badly wrong.
Atmosphere matters more than people expect
Air density changes your effective BC. A cold morning at the coast and a hot afternoon on the Highveld are genuinely different trajectories, and at longer ranges that difference is measured in feet, not inches.
This is a model, not a rangefinder. Every ballistic solver is an approximation of a real bullet in real air. Use it to get close, then confirm on paper. What matters is the drop your rifle shows with your load.
Keep the results
This calculator forgets everything the moment you close the tab. Load'Em keeps the firearm, the load, the zero and the group data together, so the trajectory is worked from what you actually shot rather than numbers you retype each time.
