Verdict Summary
If you’re looking to stock up on serious self-defense ammunition without paying a premium for boutique branding, this 500-round case of Hornady American Gunner is a solid engineering choice. It delivers the same critical XTP bullet found in more expensive Hornady lines, loaded to a higher +P pressure for increased velocity and reliable expansion. For the shooter who trains with what they carry, buying in this quantity makes practical and financial sense.
Key Features & Precision Engineering
This isn’t range fodder. Hornady built the American Gunner line to bridge the gap between premium duty ammunition and budget practice rounds. Let’s break down what you’re getting in this 500-round case.
- Hornady XTP (eXtreme Terminal Performance) Bullet: The heart of the system. This 124-grain jacketed hollow point is engineered for controlled expansion and deep penetration, a balance that’s critical for defensive use. The jacket is drawn from a solid sheet of copper, not swaged, which promotes consistent performance.
- +P Pressure Specification: The “+P” denotes higher pressure than standard 9mm Luger loads. This translates to a higher muzzle velocity—typically 50-100 feet per second more—which helps ensure reliable bullet expansion across a wider range of barriers and target distances.
- American Gunner Value Proposition: You’re getting Hornady’s proven XTP bullet in a no-frills, high-volume package. The packaging is simple, but the components and quality control are from the same source as their more expensive lines. It’s built for function, not for sitting pretty on a shelf.
- 500-Round Case Quantity: This is the real advantage. Defensive skills degrade without practice. This case quantity allows you to functionally test the ammo in your specific firearm, run several practice sessions with your carry load, and still have plenty left for duty rotation, all from a single purchase.

Pros & Cons: A Straight Shooter’s Assessment
Pros:
- ✅ Cost-Effective Defensive Ammo: At roughly $0.54 per round for a Hornady XTP load, this is a sensible price for a serious defensive cartridge.
- ✅ Proven Bullet Design: The XTP has a long track record of reliable, controlled expansion in ballistic gelatin and real-world use.
- ✅ +P Performance: The increased velocity aids expansion, especially in shorter-barreled defensive pistols which are common in the 9mm market.
- ✅ Training Quantity: A 500-round case lets you verify function and practice extensively with your actual carry ammunition, which is a critical step most shooters skip due to cost.
- ✅ Factory Fresh & Consistent: Hornady’s manufacturing ensures lot-to-lot consistency you won’t get with remanufactured or questionable import ammo.
Cons:
- ❌ Not the Latest “Bonded” Tech: The XTP is a classic, not a bonded bullet. In heavy clothing tests, some modern bonded designs may retain weight slightly better. If that’s your primary concern, see our full ammunition selection for other options.
- ❌ +P Recoil & Wear: +P ammunition generates more recoil and slightly increased slide velocity. It’s fine for modern service pistols, but I wouldn’t recommend it for older or alloy-framed guns not rated for it.
- ❌ Basic Packaging: It comes in simple cardboard boxes. If you’re looking for the fancy plastic security cases some brands use, you won’t find them here.
Who Should Buy This Ammo? (And Who Shouldn’t)
Buy this Hornady American Gunner 500-round case if:
- You carry a 9mm for self-defense and want a substantial supply of quality hollow points to train with and stock.
- You own a modern, +P-rated pistol (think Glock, SIG, Smith & Wesson M&P, etc.) and want the performance margin +P provides.
- You appreciate the value proposition—getting a major manufacturer’s proven bullet design without paying for marketing frills.
- You’re building a preparedness cache and want reliable defensive ammo in a sensible bulk quantity.
Skip this and look at an alternative if:
- You own a vintage 9mm pistol, a pistol not rated for +P pressure, or a lightweight alloy frame gun where +P wear is a genuine concern. Stick with standard pressure 9mm Luger loads.
- Your sole purpose is cheap range practice. For that, buy dedicated Full Metal Jacket (FMJ) training ammo and save the hollow points for their intended role.
- You are mandated to use a specific, often bonded, bullet design (like some law enforcement agencies). In that case, select a load that meets that exact specification.
Frequently Asked Questions
Is +P ammunition safe in my 9mm pistol?
It is safe in modern pistols explicitly rated for +P. Check your owner’s manual. Most polymer-frame service pistols from the last 25 years (Glock, SIG Sauer, Smith & Wesson M&P, etc.) are +P rated. I would avoid using it in older designs, alloy-framed guns, or sub-compacts not designed for the increased pressure and slide velocity.
What’s the difference between Hornady American Gunner and Hornady Critical Defense?
The main difference is the bullet and marketing. Critical Defense uses the FTX bullet with a polymer tip designed to prevent clogging and aid expansion, often in standard pressure loads. American Gunner uses the XTP bullet—a proven, traditional jacketed hollow point—and is often offered in +P. American Gunner is the no-frills, value-oriented line using Hornady’s core bullet technology.
Is this ammo good for concealed carry?
Yes, provided your firearm is +P rated. The 124-grain XTP at +P velocity is a legitimate and effective defensive load. The 500-round case allows you to fire a few boxes to ensure 100% reliability in your specific carry gun—a step I consider non-negotiable—and still have a multi-year supply for rotation.
How does the XTP bullet perform compared to hollow points from Federal or Speer?
The XTP is known for controlled, reliable expansion rather than maximum expansion. It tends to penetrate deeply and consistently, even through intermediate barriers. Some other designs (like Federal HST) may expand to a larger diameter in bare gel. The XTP is a classic, conservative design that has earned its reputation through dependable performance.
