Our MRR load data covers 111,585 load recipes for 13 bullets and 157 calibers. Find all bullets and reloading data below and compare the performance of different powders for each bullet and caliber combination side-by-side.
Lead-free bullets are becoming increasingly essential due to evolving legal regulations across various countries—impacting both hunting and sport shooting disciplines. Responding to this growing demand, MRR Bullets offers a range of pure copper monolithic projectiles, developed to deliver precision and high performance without compromising environmental responsibility.
MRR Bullets are the result of Sabatti’s extensive experience in the production of high-quality rifled barrels. In particular, Sabatti's expertise in manufacturing cold-hammered barrels featuring MRR (Multi Radial Rifling) technology has paved the way for the development of bullets specifically engineered to optimize ballistic performance.
Designed to match the precision standards of Sabatti's rifling technology, MRR Bullets provide outstanding accuracy, consistency, and terminal effectiveness. Their monolithic copper construction ensures high weight retention, deep penetration, and full compliance with modern lead-free requirements—making them suitable for both ethical hunting practices and precision sport shooting.

This page collects every MRR 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 MRR 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 MRR 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.
