Introduced in January 2014, the Inceptor ARX is a ground breaking projectile in every sense of the word: from the way it is manufactured, to its shape to the way it transfers energy to the target. To understand the ARX, one needs to forget nearly everything they’ve been told about projectiles. The non-expanding ARX is injection molded from a specially blended polymer-metal matrix. It is designed to penetrate most intermediate barriers without deformation and consistently achieves its terminal effect in soft targets and tissue. It is light weight; thereby producing reduced recoil and allowing for faster on-target follow up shots. The ARX design and weight also means the projectile will penetrate through half as many walls as conventional lead-core projectiles; thereby, significantly reducing the risk of collateral damage should the user miss their intended target.
From the research and development laboratory of Inceptor Ammunition, the ARX is the next-generation of hunting ammunition. Through advanced design and materials science the ARX uses fluid dynamics and non-expanding surface area instead of expansion to achieve terminal performance. The ARX penetrates straight until it encounters soft tissue. Upon entering soft tissue, the specially designed grooves in the nose harness the soft tissue and constrict, pressurize and eject it at 1.5 to 2 times the directional speed of the bullet. This is the well-known Venturi Effect. As the bullet penetrates it tumbles in a controlled, predictable fashion that delivers consistent terminal performance that rivals conventional hollow point designs. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

The information below comes from our Gun Caliber Dictionary and is for
general reference only. It does not describe the specifications of this
particular item.
The 450 Bushmaster was designed by Tom LeGendre in 2008 to bring "big bore" performance into the AR-15 platform. Hornady has adopted it as a factory cartridge. Using a .452-inch bullet, it has a case length of 2.250-inches with a rebated rim. The 450 Bushmaster propels a 250-grain bullet at 2200 feet per second, yielding 2686 foot-pounds of energy. On game the 450 Bushmaster is similar in performance to the 45-70, thus well-suited for large game such as bear, moose, and elk in close cover. Numerous AR manufacturers offer 450 Bushmaster rifles and upper receivers, and Ruger has chambered it in their bolt action M77 Scout rifle.
