About A-Square load data on XXL Reloading
This page collects every A-Square bullet we hold reloading data for, grouped by caliber and bullet weight. Each caliber and bullet combination links to a detail page with powder-by-powder load recipes: powder brand and type, start and maximum charge weight in grains and grams, case fill ratio, calculated peak chamber pressure, muzzle velocity and the barrel length the load was computed for.
Unlike a manufacturer's own tables, our A-Square data is generated with an inner-ballistics engine across the full powder range, so you can compare many powders side by side for the same bullet instead of the handful a single load manual prints. Charge weights, pressures and velocities are modelled consistently, which makes cross-powder and cross-caliber comparison meaningful when you work up a load.
Use the caliber and bullet-weight filters above to narrow the list, switch to the Bullets tab to browse the A-Square product range, and open any combination to see the full load table. All data is calculated reference data for experienced handloaders: always start at the minimum charge, work up carefully in your own rifle, and cross-check against current published data before firing.
