Firing target for firearm shooting training, comprising a bullet collecting casing mounted on a base, said casing comprising: - at least one back wall intended to capture bullets having an incidence of 0° with respect to a main firing direction, said main direction being perpendicular to a plane defined by said back wall; - at least one first set of deflecting plates arranged in front of said back wall and intended to deflect bullets having an oblique incidence with respect to said main direction, said deflecting plates being parallel to a same first plane, said first plane being perpendicular to said plane defined by the back wall; - at least one second set of deflecting plates arranged in front of the back wall and intended to deflect bullets having an oblique incidence with respect to said main direction, said deflecting plates being parallel to a second plane, said second plane being perpendicular to the first plane and inclined, by an angle a, with respect to the plane defined by the back wall, said first and second sets of deflecting plates (261, 262) being uniformly distributed inside the casing so as to define a lattice structure comprising a plurality of compartments distributed horizontally and vertically inside the casing; - at least one protective screen arranged in front of said lattice structure and intended to stop any bullet fragments produced when bullets impact against said back plate and/or said deflecting plates (261, 262), said protective screen being arranged to lean on the lattice structure and on a front face of the casing, where applicable via an additional protective curtain covering the entire rear surface of the protective screen. - at least one back wall intended to capture bullets having an incidence of 0° with respect to a main firing direction, said main direction being perpendicular to a plane defined by said back wall; - at least one first set of deflecting plates arranged in front of said back wall and intended to deflect bullets having an oblique incidence with respect to said main direction, said deflecting plates being parallel to a same first plane, said first plane being perpendicular to said plane defined by the back wall; - at least one second set of deflecting plates arranged in front of the back wall and intended to deflect bullets having an oblique incidence with respect to said main direction, said deflecting plates being parallel to a second plane, said second plane being perpendicular to the first plane and inclined, by an angle a, with respect to the plane defined by the back wall, said first and second sets of deflecting plates (261, 262) being uniformly distributed inside the casing so as to define a lattice structure comprising a plurality of compartments distributed horizontally and vertically inside the casing; - at least one protective screen arranged in front of said lattice structure and intended to stop any bullet fragments produced when bullets impact against said back plate and/or said deflecting plates (261, 262), said protective screen being arranged to lean on the lattice structure and on a front face of the casing, where applicable via an additional protective curtain covering the entire rear surface of the protective screen.
