Hasler Load Data

Hasler Bullets originated from a shared vision—and a friendly challenge—between four ballistic enthusiasts aiming to create a superior projectile. At the heart of the initiative was Giuseppe De Pasquale, an Italian record-holder and award-winning marksman, whose deep expertise and passion for precision inspired his three companions. With years of hands-on experimentation and ballistic testing behind him, De Pasquale’s innovative ideas laid the foundation for what would become Hasler's unique line of monolithic bullets.

Hasler bullets are distinguished by their undercaliber design and the incorporation of circular and semi-circular section O-rings along the projectile body. These features minimize contact between the bullet and the rifled barrel, significantly reducing friction—similar to the principles used in high-caliber artillery shells. This advanced engineering results in improved velocity, reduced barrel wear, and superior ballistic performance.
Designed and manufactured in Italy, Hasler monolithic bullets are crafted to meet the highest standards of accuracy, consistency, and environmental responsibility. With their solid copper construction and aerodynamic profiles, they are ideal for hunters and long-range shooters seeking precision and ethical, lead-free performance.
