Who We Are?

Tradition with an Industrial Spirit

Montorretas is a family-owned company, founded by Don Lino Oskoz, with a strong industrial spirit. Since our beginnings, we have perfected the manufacture of lead shot for hunting and competition, becoming a European benchmark for the cartridge industry. Experience, innovation, and loyalty to our roots have defined us for more than six decades.

Precision in Constant Evolution

At Montorretas, we believe that perfection is never improvised: it is built, inherited, and improved day after day. Thanks to a versatile and efficient production system, our team and machinery can quickly adapt to new demands while maintaining the highest quality in every grain of lead.
