4.4x55mm AMJ Custom
Overview
4.4x55mm AMJ Custom is an extreme long range wildcat cartridge constructed using a 12.7x55mm casing necked down to .17 HMR/4.4mm projectiles. It is capable of reaching extreme velocities but due to the limited mass of the projectiles it does not offer enormous amounts of damage down range.
Stats
