Why This Eley Ammo Belongs in Your Range Bag
For over a decade, I’ve seen shooters chase accuracy with their .22s, only to be let down by bulk ammo that can’t hold a group. Eley didn’t just make another target round. They built this Semi-Auto Benchrest Precision from the ground up for the unique demands of self-loading actions. The 40-grain round-nose profile is optimized for reliable feeding from a magazine, while the priming and propellant are tuned for minimal velocity variation—that’s where those tiny groups come from. This is the ammo you use when you want to know exactly what your rifle is capable of, without the frustration of a failure to feed or eject. It’s the practical choice for the shooter who values every round, whether you’re practicing your concealed carry drills with a .22 counterpart or teaching a new shooter the fundamentals.

The Good and The Honest Truth
Pros:
- ✅ Unmatched Semi-Auto Reliability: Engineered to feed, fire, and eject flawlessly in self-loading actions, reducing malfunctions to near zero.
- ✅ Benchrest-Grade Accuracy: Delivers the tight group sizes Eley is famous for, letting your rifle’s true potential show.
- ✅ Exceptional Lot Consistency: Velocity and pressure are tightly controlled from round to round and lot to lot, so your zero stays true.
- ✅ Sealed for Storage: The sealed primer and case mouth protect against moisture, making it a great choice for your long-term ammo stash.
- ✅ Ideal for Training: The perfect practice ammo for centerfire drills when matched with a dedicated .22 trainer.
Cons:
- ❌ Premium Price: This isn’t bulk plinking ammo. You’re paying for precision engineering and consistency. If your goal is just making noise on steel, our standard velocity rimfire options offer better value.
- ❌ Not for Every .22: Some extremely tight-chambered match rifles (designed for single-feed) may not cycle it as intended. It’s built for function in semi-autos first.
Who Should (and Shouldn’t) Buy This Ammo
Buy it if: You own a semi-automatic .22 rifle or pistol (like a 10/22, Mark IV, or AR-15 in .22) and you’re serious about accuracy. If you use a .22 for meaningful practice—whether for hunting small game, competitive shooting, or defensive drills—this ammo removes variables. It’s also a smart buy for the shooter who appreciates having a case of supremely reliable, accurate ammo on hand that won’t degrade over time.
Skip it if: Your .22 is purely a “plinker” for cans and reactive targets at 25 yards, and you go through 500 rounds an afternoon. The cost per round won’t make sense. Also, if you shoot exclusively bolt-action target rifles where ultimate precision is the only goal, you might lean toward Eley’s dedicated benchrest tennex line. For general fun and familiarization, we have plenty of other effective options.
Common Concerns, Answered
“Will this cycle in my stock 10/22?”
In nearly all cases, yes. That’s its primary design purpose. We’ve tested it in dozens of common semi-autos with excellent results. The 40-grain round nose is the most reliable feeding profile.
“Is it good for hunting?”
The accuracy certainly is. The 40-grain round nose is a proven small game projectile. Where legal and ethical, its consistency makes for precise shot placement on squirrels and rabbits.
“How does it compare to standard Eley Target?”
The Semi-Auto Benchrest Precision uses a slightly different powder burn rate and priming to ensure positive cycling in self-loaders, where standard Target ammo is optimized for ultimate accuracy in any action type, sometimes at the expense of 100% cycling energy.
Frequently Asked Questions
Is this ammo subsonic?
This depends on your barrel length. In most rifles with 16″+ barrels, it will likely be supersonic, producing a mild crack. In shorter pistol barrels, it often stays subsonic, making it an excellent choice for suppressed use where cycling is critical.
Can I use this in a bolt-action rifle?
Absolutely. It will fire and be very accurate. However, its specific tuning for semi-auto cycling isn’t a benefit in a bolt action. You’re paying for a feature you won’t use, so a dedicated target ammo might be a better fit for pure bolt-gun accuracy.
How is the accuracy at 50 and 100 yards?
Outstanding for a semi-auto focused round. At 50 yards, expect dime-sized groups from a good rifle. At 100 yards, it holds together well, though wind drift on the 40-grain bullet becomes a significant factor, as with any .22 LR.
Is the primer corrosive?
No. Like all modern Eley ammunition, this uses non-corrosive, non-mercuric primers. You can clean your firearm with standard procedures.
What does “Rou…” mean in the product name?
That’s an abbreviation for “Round Nose,” describing the projectile shape. The round nose profile is chosen specifically for its reliable feeding characteristics in magazine-fed semi-automatic firearms.

Yes, particularly in semi-auto focused competitions like some NRL22 base classes or practical pistol events. Its reliability is as valuable as its accuracy in a timed match where a malfunction can cost you the stage.
