Underwood Ammo 627 ASP 460Rowland 185gr Jacketed Hollow Point 20 Per Box/10 Case

The Underwood Ammo 627 ASP 460 Rowland 185gr Jacketed Hollow Point round combines precision defense ammunition engineering with real-world stopping power. Built on Nosler's Assured Stopping Power (ASP) projectile platform, these rounds are purpose-designed for hunters and shooters who demand reliable expansion without sacrificing accuracy or consistent feeding. Each 20-round box ships as part of a 10-box case, giving you the volume you need for serious practice or carry rotation in your 460 Rowland handgun.

The ASP bullet's signature deep skives are engineered to do two things at once: create rapid, repeatable expansion while maintaining reliable chambering and feeding across all action types. That controlled expansion means your energy transfer is optimized, and over-penetration—a real concern in defensive scenarios—is minimized. This is particularly important in the 460 Rowland, where velocity and energy levels demand a projectile that can handle the terminal performance demands of the cartridge.

Underwood pairs the ASP projectile with nickel-plated brass casings, a step many budget ammunition makers skip. The nickel plating improves feeding reliability, resists corrosion far better than plain brass, and won't tarnish during storage or when exposed to moisture, leather, or other metals. The casings are also easier to clean during reloading. All of this rounds out with Underwood's flash-suppressed powder formula—a critical feature if you ever need to use your firearm in low light and still maintain your vision.

Whether you're developing a reliable carry load, training at the range, or hunting with a 460 Rowland, this ammunition reflects thought-through ballistics engineering rather than generic commodity production.

Specifications

Frequently Asked Questions

What firearms does the 460 Rowland round work in?

The 460 Rowland is a proprietary cartridge based on the 45 ACP case. Compatibility depends on your specific 460 Rowland firearm—confirm your gun's compatibility with the ammunition manufacturer before purchase. Underwood builds these rounds for reliable feeding in firearms chambered for 460 Rowland.

Is this ammunition suitable for self-defense or carry?

Yes. The ASP bullet and flash-suppressed powder are specifically designed with defensive use in mind. The controlled expansion addresses stopping power while minimizing over-penetration, and the flash-suppressed formula preserves your vision if you need to fire in low-light conditions.

Can I reload these brass casings?

Yes. The nickel-plated brass is built for reloading, and Underwood specifically designed the cases to be easier to clean during the reloading process compared to traditional brass.

What is the ASP bullet, and why does it matter?

The ASP (Assured Stopping Power) is a Nosler-engineered hollow-point projectile featuring deep skives in the jacket. These skives allow the bullet to expand reliably and consistently while still feeding reliably in your firearm and transferring energy effectively to your target.
