The Inceptor Preferred Hunting line features our patented ARX bullet, a non-expanding projectile that is lighter, faster and has low recoil while retaining a flat trajectory. Its fluted design ensures exceptional reliability and terminal performance. The ARX is a universal hunting projectile. The projectile is injection-molded from a specially blended polymer-copper matrix that is designed to be tough enough to penetrate soft tissue. And when it encounters tougher barriers, it breaks apart to reduce the risk of over-penetration.


Patented hunting technology - from the research and development laboratory of Inceptor Ammunition, the Inceptor ARX is the next-generation of hunting ammunition
Patented hunting technology - through advanced design and materials science, the ARX uses fluid dynamics and non-expanding surface area instead of expansion to achieve terminal performance
Engineered fluid dynamics - hydraulic displacement produces devastating wound channels rivaling and exceeding traditional expanding bullets
Lateral force - after entering soft tissue, the specially designed grooves in the nose of the non-expanding ARX projectile constrict, pressurize and eject fluid at 1.5 to 2 times the directional speed of the bullet
Lateral force - the polymer-copper bullet is also tough on bone and provides excellent knockdown power through superior terminal effects
Specially engineered profile - because it has no hollow-point or sharp edges on the nose of the bullet, the ARX feeds like a round nose, yet retains stopping power and terminal performance that exceeds many expanding handgun bullets
Precise - injection-molded ARX projectiles deliver exceptional accuracy
High velocity - achieves higher velocity and higher energy, yet imparts less recoil for quicker follow-up shots
Advanced materials - performs in a wide range of conditions and weapons systems
