Its unique design -- High Tech

1 The boat tail design reduces air drag. This allows the bullet to better retain its velocity for better terminal performance.

the core of the GPA bullet2 The core weighs from 60% to 75% of the bullet.

3 The specially designed driving belts provide maximum rotational stability while reducing copper fouling. Their depth perfectly matches the diameter of the bottom of the rifling grooves, and their thickness guarantee complete gas check, thereby reducing bore erosion and eliminating bullet deformation in the barrel.

4 The crimping groove guarantees that bullets in the other loaded cartridges in the rifle will not move during recoil. It also serves as a pre-cut for petals separation.

5 The pilot belt is essential for the geometry of the bullet and its perfect presentation in line with the bore axis. This results in improved accuracy.

6 The sharp edge on the nose provides for clean-cut entry holes.

7 The conic pointed nose has the same diameter as the top of the rifling lands in the barrel. It guides the bullet in the bore without engaging the rifling.

8 The caliber specific wide hollow point in cavity is about 1/3 the length of the bullet. It favors the expansion and the creation of the petals.

9 The petals precuts initiate the expansion then fragmentation of the petals.

10 The caliber specific conic shape of the hollow point mouth ensures expansion after penetration.
