Popular Ammo Offerings from Underwood

  • 10mm:The 10mm Auto, often referred to as 10mm, is a potent handgun cartridge that was introduced in 1983. When compared to standard, non-specialty .357 Magnum loadings, the 10mm Auto is capable of producing higher energies. Specialty 10mm Auto loadings are on par with specialty, high performance .357 Magnum loadings. The cartridge is often compared to the 9mm Luger and .45 ACP as they were common semi-automatic cartridges of the time. The 10mm Auto essentially has high velocities, like 9mm Luger, and larger, heavier projectiles, like .45 ACP, providing shooters with a versatile and capable round. The 10mm Auto will notably have a stout and snappy recoil impulse which is accompanied by flat trajectories.
  • 9mm:The 9mm Luger cartridge is easily the most common handgun round in common use. The caliber goes by many names, often being referred to as 9mm NATO, 9mm Parabellum, 9x19mm, or just generically “9mm”. The cartridge’s origins can be traced back to the early 20th century and is the brainchild of Georg Luger. Originally found in firearms such as the Borchardt C-93 and the P-08 Luger pistol, the round has become a common chambering for handguns in civilian and military use from the 20th century onward. Firearms such as pistols and submachine guns in 9mm Luger have commonly been used by military and law enforcement personnel across the globe, leading to the round establishing a reputation for being a reliable service cartridge.
  • .44 Magnum:The .44 Magnum was developed by Elmer Keith and Smith & Wesson in the 1950s alongside the Model 29 revolver. Known for its powerful recoil and impressive stopping power, the .44 Magnum was popularized in mainstream culture through films like Dirty Harry. Today, it remains a popular choice for handgun hunting, plinking, and self-defense.
  • .50 AE:The .50 Action Express (AE) was developed in 1988 by Evan Whildin of Action Arms and quickly gained attention as one of the most powerful commercially available pistol cartridges on the market. It is best known for its use in the Desert Eagle pistol. With bullet weights typically ranging from 300 to 500 grains, the .50 AE provides a significant impact on target with staggering levels of energy transfer.

Common Underwood Bullet Types

  • Full Metal Jacket (FMJ):Like the name suggests, these types of loadings feature projectiles which are adorned with metal jacketing. This jacket is generally made of copper and will cover the tip and sides of the projectile. Typically, the base of the projectile is left uncoated. These types of loadings are well-suited for range use and are some of the most common types of ammo one will encounter.
  • Jacketed Hollow Point (JHP):JHP loadings feature hollow point projectiles which are adorned with a full metal jacket. These loadings are generally found in the form of defensive ammo offerings and are designed to facilitate reliable expansion upon impact. Additionally, these types of loadings are designed to achieve adequate levels of penetration for defensive purposes while not overpenetrating the target and risking collateral damage. A good hollow point loading is one that achieves an appropriate level of penetration while expanding reliably upon impact within the target.
  • Wadcutter (WC):These loadings feature bullets with a completely flat nose and cylindrical profile designed to cut precise, full-caliber holes in paper targets for optimal scoring accuracy. Developed specifically for competitive target shooting, the Wadcutter bullet incorporates a flat front face that creates clean, easily measured holes in paper targets while providing exceptional accuracy potential at close ranges typical of bullseye competition. The WC design provides superior target cutting performance and scoring precision compared to other bullet profiles while offering consistent accuracy for competitive applications. These types of loadings are well-suited for bullseye competition, precision target shooting, and competitive applications where clean target holes, maximum scoring accuracy, and exceptional precision are essential for competitive success and accurate measurement.
