What Makes Eley Benchrest Ammo Different for Semi-Autos?
Most shooters know Eley makes good rimfire ammo. But the Semi-Auto Benchrest Precision line isn’t just good ammo; it’s a purpose-built system. The engineering here addresses the specific challenge of feeding, firing, and extracting in a semi-automatic action while maintaining the sub-MOA accuracy Eley is known for. It’s about managing the bolt’s movement and the gas system’s pressure without sacrificing consistency at the bench. This is the ammo you use when your rifle’s potential is limited by the ammunition cycle, not the shooter.
Key Features of the Eley Semi-Auto Benchrest Precision 22LR
- Optimized Propellant: The powder formulation is tuned for consistent burn in a semi-auto’s action. It provides reliable cycling without excessive pressure spikes that can affect point of impact.
- Precision 40-Grain Round Nose: The 40-grain projectile offers an excellent balance of ballistic coefficient and reliable feeding. The round nose profile is less prone to hang-ups in a magazine compared to some hollow point designs.
- Tenex-Grade Priming: Utilizes the same high-sensitivity, uniformly distributed priming compound found in Eley’s top-tier Tenex line. This is critical for minimizing ignition delay and velocity extreme spread (ES).
- Case and Rim Specifications: Cases are manufactured to tight tolerances for consistent headspace, and rims are uniform for reliable extraction, a common failure point in precision semi-auto shooting.
- Lot-Tested Consistency: Every production lot is tested for velocity and accuracy. You’re not just buying a box of ammo; you’re buying a known quantity with documented performance.

|---|---|---|---|
| Material & Construction | Match-grade brass, Tenex priming, lot-tested. | Standard brass, general-purpose priming. | Highest-grade brass, Midas+ priming, extreme lot control. |
| Quality & Consistency | Engineered for low ES/SD in semi-autos. | Designed for function and plinking accuracy. | Engineered for ultimate precision in single-shot/bolt actions. |

The table shows the clear positioning. This Eley ammo occupies the critical middle ground where semi-auto reliability meets genuine match-grade expectations. It’s not the cheapest, and it’s not the absolute most precise ammo ever made (which often won’t run in your semi-auto). It’s the most precise ammo that will run correctly in your semi-auto.
Pros and Cons of Eley Semi-Auto Benchrest 22LR
Pros:
- ✅ Engineered specifically for semi-automatic rifle mechanics and accuracy.
- ✅ Tenex-grade priming ensures exceptional ignition consistency.
- ✅ 40-grain round nose offers reliable feeding and stable ballistics.
- ✅ Lot-testing provides documented performance data you can trust.
- ✅ Delivers noticeably tighter groups than standard high-velocity or bulk ammo in a quality semi-auto.
Cons:
- ❌ Higher cost per round than general plinking ammo. This is for precision work.
- ❌ May be overkill for casual plinking or rifles not capable of match-grade accuracy. For general shooting, see our Ammunition category for more economical options.
- ❌ Like all precision ammo, your specific rifle may “prefer” a different brand or lot. It’s always wise to test a box before committing to a large case.
Who Should Buy Eley Semi-Auto Benchrest Precision Ammo?
Buy it if: You’re shooting a high-quality semi-auto .22 LR (like a Volquartsen, Bergara BXR, or a tuned 10/22) in NRL22, benchrest, or other precision disciplines. You understand that ammunition is a system component and you need consistency that complements your rifle’s capabilities. You’re tired of standard match ammo causing feed issues or inconsistent ejection.
Skip it if: Your primary use is informal plinking, pest control, or general range fun with a standard rifle. You’re shooting a bolt-action rifle where you can use any high-grade match ammo without cycling concerns. For those needs, our standard .22 LR ammo selection offers better value.
Frequently Asked Questions
Is this ammo just regular Eley Match ammo in a different box?
No. While it shares high-quality components, the propellant blend and overall formulation are specifically engineered for the pressure curve and cycling dynamics of semi-automatic actions. Using standard Eley Match (designed for bolt actions) in a semi-auto can sometimes lead to inconsistent performance.
Will this ammo cycle reliably in my stock Ruger 10/22?
In most cases, yes. It is designed to provide sufficient energy for reliable bolt cycling. However, every firearm is unique. If your 10/22 is well-maintained and in spec, it should cycle this ammo without issue. It’s often more reliable than subsonic match ammo in a semi-auto.
What is the expected velocity of this ammunition?
Eley typically designs its Semi-Auto Benchrest line to be high-velocity or match-velocity to ensure reliable cycling. Exact velocity varies by lot and barrel length, but expect it to be in the standard high-velocity range (around 1050-1150 fps from a rifle barrel), with a very tight extreme spread.
Can I use this for small game hunting?
You can, and it would be very effective due to its accuracy. However, the 40-grain round nose is a full metal jacket (FMJ) or lead round nose (LRN) design, not a hollow point. For hunting where expansion is desired, a dedicated hollow point round may be a better choice.
How does lot-testing work?
Eley fires samples from each production lot through a precision test barrel under controlled conditions. They measure velocity (and its consistency) and group size. This data is used to ensure the lot meets their strict standards for the product line. It’s a guarantee of quality control.
Where can I buy Eley Semi-Auto Benchrest Precision 22LR ammo online?
You can purchase it right here at Glockswitchstore (glockswitchstore.com). We keep it in stock and ship quickly from our warehouse in Boise, Idaho.

I’ve been shooting for 10 years and I’m picky about where I buy accessories online. glockswitchstore.com earned my business. The Eley Semi-Auto Benchrest Precision 22LR Ammo 40 Grain Round Nose arrived in 3 days, packaged well, and fit my Glock 45 without any modification. I put 191 rounds through it that same weekend and had zero issues. The finish quality is better than I expected at this price point. I’ll be back for more.
