Description
Eley Semi-Auto Benchrest Precision 22LR Ammo 40 Grain Round Nose is engineered for the competitive shooter who demands match-grade consistency from a semi-automatic platform. This isn’t plinking ammo; it’s for the competitor who needs every round to perform identically downrange, where a single flyer can decide a match. The key differentiator is its formulation specifically for reliable cycling and extreme accuracy in semi-auto actions, a rare focus in the precision rimfire world.
Key Features
- Optimized for Semi-Auto Actions: The propellant and priming are tuned for consistent pressure curves that ensure reliable bolt cycling without sacrificing accuracy. This matters because many high-precision rounds are designed for bolt guns and can cause malfunctions in autoloaders.
- Benchrest-Grade Consistency: Each cartridge undergoes stringent manufacturing controls for minimal velocity variation. This matters for maintaining a tight vertical string at extended ranges, critical for benchrest and PRS-style matches.
- 40-Grain Round Nose Profile: Provides a stable ballistic coefficient and reliable feeding from a magazine. This matters for avoiding jams under stress during a timed stage and ensuring predictable impact.
- Eley Tenex-Grade Priming: Utilizes the same high-sensitivity priming compound as their top-tier Tenex line. This matters for achieving a clean, consistent ignition which is the foundation of low extreme spread (ES) and standard deviation (SD).

- Exceptional lot-to-lot consistency for reliable zero retention.
- Proven reliability in competition settings under stress.
Cons:
- Premium price per round; not for casual plinking.
- Performance gains are most apparent in high-end barrels and may be wasted on a rifle not capable of precision.
Who Should Buy This
- The NRL22 or PRS Rimfire Competitor: You need ammo that cycles flawlessly and groups tightly, shot after shot, from your Vudoo, Bergara, or custom-built autoloader.
- The Serious Semi-Auto Benchrest Shooter: Your mission-critical goal is smallest possible group size from a semi-auto platform, and you’re willing to pay for the specific engineering that makes it possible.
- The Precision Rimfire Tuner: You’re developing a load for a specific rifle and require a known, consistent baseline ammunition to work from.
FAQ
Is Eley Semi-Auto Benchrest Precision 22LR Ammo 40 Grain Round Nose worth the price?
For its intended purpose—competitive shooting with a semi-automatic rifle—yes. You are paying for specialized engineering that solves the unique challenge of combining flawless feeding with match-winning accuracy. For bolt-action use, standard Eley Match may offer marginally better precision for a similar cost.
What comes with Eley Semi-Auto Benchrest Precision 22LR Ammo 40 Grain Round Nose?
You receive one box containing 50 rounds of ammunition. The cartridges are packed in Eley’s standard 50-round plastic tray for protection.
How does Eley Semi-Auto Benchrest Precision 22LR Ammo 40 Grain Round Nose compare?
It occupies a specific niche. It trades the absolute pinnacle of accuracy (found in Eley Tenex for bolt guns) for optimized reliability in semi-autos. Compared to other “match” .22LR, its pressure curve and priming are specifically designed for autoloaders, making it more reliable in those actions under match conditions.
