ALSA PRO s.r.o. is a manufacturer of full metal jacket (FMJ) bullets and reloaded ammunition, with a production legacy rooted in extensive hands-on experience. Initially, in 2010, the company focused primarily on the 9mm LUGER cartridge, leveraging over two decades of expertise in reloading and ammunition manufacturing.
This foundational experience was provided by Pavel Marcinek, the company’s founder, who had previously produced ammunition both for private use and on an industrial scale. His background laid the groundwork for the company’s transition into full-scale commercial manufacturing.
Since 2011, ALSA PRO has specialized in the production of 9mm full metal jacket bullets, steadily expanding its offerings to meet the increasing demand for this caliber across various shooting disciplines. A major milestone was achieved in 2015 with the installation of a new production line, which significantly increased output capacity.
ALSA PRO is committed to delivering exceptional quality and precision, ensuring that every product meets the rigorous standards required by customers across Europe. Each stage of production is guided by a focus on reliability, consistency, and performance.

About ALSA PRO load data on XXL Reloading
This page collects every ALSA PRO 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 ALSA PRO 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 ALSA PRO 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.
