The Story
ATP KING 40gr 5.52mm .22
A new type of patented airgun turned lead slugs for the 21st century Altaros ATP. New version 40gr, BC 0.21!
ATPĀ 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. ATPĀ slugs achieve a high ballistic coefficient ofĀ 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.Ā Slugs made with this technology currently hold a world record ofĀ hitting target onĀ 1400 yardsĀ from an airgun!
Ā
The recommended muzzle velocity is around 280 m/s - 900 fps and lower. The maximum speed is up to 300 m/s (up to 980 fps)!
Parameters of SLUGS:
- Ballistic coefficient BC 0.21 (function G1)
- Diameter - 5.52 mm .2173"
- Weight - 2.6g -Ā 40 grain
- Length - 11.4mm 0.45"
- Quantity 110 pcs
Properties:
- High precision
- Precise shape
- Perfect symmetry and balance
- Longer shape for better guidance in the barrel which contributes to higher accuracy
- The highest ballistic coefficient on the market BC 0.21 (function G1 at muzzle velocity 250 m/s)
- Extremely low weight differences -Ā Significantly improvedĀ muzzle velocity consistency
- Peripheral grooves for reduced friction allow easy insertion into the barrel
- Packed individually in extremely durable packaging.
