Built for Shooters Who Want Answers

Every shooter has been there: you're trying to pick between two factory loads and end up wading through 47 forum threads, each with a different “expert” opinion. Load Lab exists so you can skip the noise and look at the numbers.

We pull ballistic specifications directly from manufacturer data — muzzle velocity, ballistic coefficients, bullet weight, energy — and let you compare them side by side with interactive trajectory, velocity, energy, and wind drift charts. Pick your loads, set your conditions, and see exactly how they stack up from the muzzle to your max range. All comparisons are based on published manufacturer specifications. We don't independently verify them, and we say so — because transparency about where the data comes from is the only way to trust what it shows.

The ballistic solver uses standard G1 and G7 drag models to calculate trajectories, accounting for atmospheric conditions, zero distance, and wind. It's the same math the expensive apps use — we just don't charge for it.

Load Lab's analysis starts with manufacturer-supplied specifications — the same numbers that are publicly available, pulled together in one place and examined honestly. When there's a known gap between what a manufacturer publishes and what shooters are seeing in the field, that gap is part of the story. Our tools let you adjust inputs like muzzle velocity to reflect real-world conditions, so the data works for you, not against you.

Ballistic data tells you what's possible. It can't tell you what's probable for a specific shooter in a specific field condition. A trajectory chart can show you retained energy at 400 yards. It can't account for shot placement, animal angle, wind gusts, or the shooter behind the trigger. Load Lab is built to give you the best possible information — and to be honest about everything that information can't measure.

The decision belongs to the shooter. Always.
