ATP KING 40gr 5.50mm .22

Reference ATPK-5.50-110

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!

In addition to his own success, he led the Italian team to first place in the Unlimited Airgun Benchrest team competition, thanks to his personal result and also sharing his perfectly tuned shooting system (airgun and slug) with his two team shooters, who took 4th and 5th place with 730 and 727 points, respectively, a difference of only X in the first case. We are very proud that Mr. Atzeni and his team have placed their trust in our ATP King 40 gr 5.52 and we are glad that we could be part of his success.

The Italian team took first place with a commanding lead of almost 50 points against the second team from South Africa. Congratulations also to the South African shooters for their second place, with the first two shooters in particular delivering an amazing shooting performance.

And of course, congratulations to the Lebanon team for their third place, who had very consistent results, and we are also pleased that the Lebanon team also used our ATP King slugs. We would also like to congratulate all the top 10 competitors, as the results were very close and high, considering that the shooting range was windy and we are pleased that 50% of the top 10 shooters chose our ATP King 40gr slugs.

From the information we receive from shooters, other shooters outside the top 10 often used our slugs. We would also thank these shooters for placing their trust in our slugs.

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.
