How the GPA bullet works : Expansion and Fragmentation

After complete expansion the petals separate from the bullet shank and become secondary projectiles.
Separate wound channels in a 5" (10 cm) radius around the main wound channel

Upon impact two different effects take place:

1- Controlled expansion of the hollow point.

The solid alloy construction prevents expansion from happening immediately upon impact. This ensures deep penetration. Then, the precuts machined in the nose cavity allow for massive expansion of the petals over a very wide range of impact velocity. This ensures maximum energy transfer.

2- Controlled fragmentation of the petals.

After complete expansion the petals separate from the bullet shank near the crimping groove and become secondary projectiles, creating separate wound channels in a 5" (10 cm) radius around the main wound channel.

The two successive effects, expansion then fragmentation, produce massive and multiple traumas, leading to instant kill. Each of the petals typically expands 100% of its energy in the animal's body and remains in it, while the bullet core retains typically about 60% to 75% of its initial weight and continues to penetrate and mushroom, achieving complete penetration and providing the 2 to 3 caliber exit hole that is necessary if tracking is required.
