Why This Hornady Critical Defense 22 WMR is a Smart Choice
Let’s be honest, most .22 WMR ammo on the shelf is designed for plinking or varmints. If you’re considering a rimfire pistol or revolver for a concealed carry lifestyle or as a backup, you need ammunition you can trust. That’s where this Hornady load comes in. It’s not just another box of rimfire; it’s engineered from the ground up for defensive scenarios. The 45-grain FTX bullet with its polymer Flex Tip is designed to initiate consistent expansion through heavy clothing, something most .22 WMR rounds simply won’t do. Having handled and recommended this ammo for years, I see it as a serious option for those who want a lightweight, low-recoil defensive firearm without sacrificing terminal performance.

The Real-World Pros and Cons
What you’ll appreciate:
- ✅ Engineered Expansion: The Flex Tip design helps the hollow point open reliably, even through denim or heavy fabric, which is critical for defensive use.
- ✅ Consistent Performance: Hornady’s quality control means more reliable ignition and velocity consistency than some bulk rimfire ammo.
- ✅ Low Recoil Advantage: In a lightweight revolver or pistol, follow-up shots are fast and manageable, a real benefit for some shooters.
- ✅ Serious Rimfire Option: It legitimizes the .22 WMR as a viable defensive caliber choice when other options aren’t suitable.
- ✅ Great for Training: The shooting characteristics allow for affordable, low-recoil practice that’s closer to your defensive routine than standard .22 LR.
What to consider:
- ❌ Cost Per Round: At this price, it’s for serious use, not plinking. For high-volume practice, you’ll want standard ammo. See our rimfire ammo for training options.
- ❌ Rimfire Limitations: It’s still rimfire. While Hornady’s priming is excellent, it doesn’t have the absolute ignition reliability of a centerfire primer. Have a backup plan.
- ❌ Not a Varmint Round: This is designed for defense. For prairie dogs or raccoons, a varmint-specific load is more appropriate. Browse our hunting ammunition.
Who Should (and Shouldn’t) Buy This Ammo
Buy it if: You carry a .22 WMR revolver or pistol for personal defense and want the best-performing ammunition available for it. It’s also a smart buy for someone with recoil sensitivity who has settled on .22 WMR as their primary defensive caliber, or for a budget-conscious shooter who wants to stock a limited amount of high-quality defensive ammo for a backup gun.
Skip it if: You’re just looking for ammo to shoot tin cans or hunt ground squirrels—this is overkill and too expensive for that. Also, if absolute, 100.00% ignition reliability is your non-negotiable top priority, you should be looking at a centerfire caliber. Check our full shop for other caliber options.
Common Concerns & Straight Answers
Q: Is .22 WMR really powerful enough for self-defense?
A: With the right shot placement and a bullet that expands like this Hornady FTX, it can be effective. It’s a legitimate choice for those who cannot handle more recoil or need a very small, lightweight firearm. It’s better than a .22 Long Rifle and far better than being unarmed.
Q: Will this ammo cycle in my semi-auto .22 WMR rifle?
A> It should cycle in most firearms chambered for .22 WMR, as it’s loaded to standard pressures. However, always test a box in your specific firearm to ensure function before relying on it.
Q: Why is it so much more expensive than other .22 WMR?
A> You’re paying for the advanced bullet engineering (the FTX tip), higher quality control standards for consistency, and the R&D that went into making a rimfire round perform like a defensive centerfire round.
Frequently Asked Questions
What is the bullet design in Hornady Critical Defense 22 WMR?
It uses Hornady’s FTX (Flex Tip eXpanding) bullet. A polymer tip fills the hollow point cavity, preventing clogging from clothing and initiating more reliable and consistent expansion upon impact.
Is this ammo suitable for a small-frame revolver?
Yes, that’s one of its primary intended uses. Revolvers like the Smith & Wesson 351C or Ruger LCR in .22 WMR are common carriers for this ammunition due to their lightweight and simple operation.
What is the velocity of this round?
Hornady lists a muzzle velocity of approximately 1,500 feet per second (fps) from a pistol-length barrel. Velocity will be higher from a rifle barrel, but defensive performance is typically rated from handgun lengths.
Can I use this for hunting?
While it would be effective on small game, it is specifically engineered for defensive use. For hunting, a varmint or small game load is usually a better choice as it’s designed for different terminal performance.
How does it compare to .22 LR defensive ammo?
The .22 Winchester Magnum Rimfire case holds more powder, generating significantly higher velocity and energy than .22 Long Rifle. This, combined with the FTX bullet, makes it a more capable defensive round than even the best .22 LR options.
