AI-Assisted Load Discovery

GenAI Reloading Tool (GRT)

This tool is ideal for reloaders who are not yet set on a specific cartridge, bullet, or powder combination. Use it to explore suitable bullets and load recipes for your target cartridge. Once you have a shortlist, you can fine-tune your setup with our calculators to maximize performance and accuracy.

For supersonic loads only and shows powders / recipes only that fulfill the following criteria: Powder Burn > 98%, Fill Rate 80-100%, Max Pressure ≤ 90% of max. allowed pressure. Click on the calculator icon to load the recipe into the standard calculator for fine-tuning or to adjust parameters.

Internal Ballistics

Simulate chamber pressure, muzzle velocity and barrel time for any load recipe.

Trajectory

Calculate long-range trajectory, drop, drift and energy with G1/G7 ballistic coefficients.

Parametric Powder Search (PPS)

Find the best powders for your caliber and bullet based on fill rate, pressure and velocity.

Optimal Barrel Time (OBT)

Tune your load into an OBT node for tighter groups and lower vertical dispersion.

Target Velocity

Reverse-engineer the powder charge required to hit a target muzzle velocity — perfect for subsonic loads.

Powder Temperature Sensitivity

See how powder temperature swings from -19 °C to 51 °C affect pressure and muzzle velocity.

Load Comparison

Compare up to three saved diary loads side-by-side across charge, velocity, pressure and accuracy.
