A new type of patented airgun turned lead slugs for the 21st century Altaros ATP. New version 40gr, BC 0.21!

ATP slugs are manufactured by using unique lead turning technology on a precision CNC machine that Altaros has developed first in the world. Slugs produced by this technology have very precise dimensions resulting in almost zero weight difference with excellent axial symmetry. That can't be achieved by any other method currently used. ATP slugs achieve a high ballistic coefficient of BC 0.21, which is the highest on the market.

These key features predetermine ATP to achieve maximum accuracy and stability when shooting at tens or hundreds of meters. Slugs made with this technology currently hold a world record of hitting target on 1 MILE from an airgun!

Altaros M24 with ATP KING 5.50

Extremely durable packaging:

Packed with emphasis on the maximum safety of slugs during transport. The slugs are seated individually in a resilient foam that absorbs shocks. The entire package is vacuumed, thus pressing the two halves of the package firmly and preventing slugs from moving in any way. This will prevent their mutual compression and deformation. In this package, the slugs retain a perfect turned shape even after a long, difficult journey and rough handling.

Package tested by 17 feet (5 m) drop test

The appearance of the surface of the slugs may vary from one package to another, but this does not affect functionality or accuracy.
