How Should You Read .22LR Ammunition Reviews?
Ammunition reviews are useful, but they answer a narrower question than most readers assume. A review that tests one box of one batch in one rifle on one day tells you how that pairing performed. It does not tell you how the product will perform in your rifle.
This is not a criticism of reviewers. It is a consequence of how rimfire accuracy works. Every barrel has its own unique characteristics, and each batch of ammunition performs differently. What performs flawlessly in one barrel may not deliver the same results in another.
The good news is that you do not have to rely on interpretation. For ELEY ammunition, the underlying test data is published, and you can generate your own.
What a Review Can and Cannot Tell You
A review can tell you how a product feeds and chambers, how clean it runs, how the packaging holds up, what the velocity measured in that reviewer’s rifle, and whether the product exists in the form advertised.
A review cannot tell you how a different batch of the same product will shoot in a different barrel. That is a two-variable problem, and a single-lot single-rifle test holds neither variable in a way that transfers.
This is why ELEY does not ask shooters to rely on reviews. It publishes the numbers instead.
Three Sources of Objective ELEY Data
1. The published accuracy standard for every product.
ELEY grades on Radial Standard Deviation, which measures the distance from each shot hole to the group’s centre point, the mean point of impact. Unlike extreme spread, which considers only the two furthest shots, RSD evaluates every shot fired, which is what makes it statistically robust.
| Product | Maximum RSD |
|---|---|
| ELEY tenex | 3.75 mm |
| ELEY ultra extreme long range | 4.00 mm |
| ELEY tenex pistol | 4.40 mm |
| ELEY tenex biathlon | 4.50 mm |
| ELEY match | 4.74 mm |
| ELEY semi-auto benchrest precision | 4.90 mm |
| ELEY team, club, biathlon club | 5.50 mm |
| ELEY sport / target, force, contact, semi-auto benchrest outlaw, bullseye pistol x | 7.00 mm |
Every batch must meet the standard for its grade. ELEY tests 200 rounds from every batch across four different firearm brands to calculate the figure.
2. The Lot Analyser: ELEY’s own proof data, free.
Create a free account at eleyxshot.com and enter the batch number from the end panel of your box. For all lots of ELEY tenex, tenex pistol, tenex biathlon, tenex rapid fire pistol, match, semi-auto .22LR benchrest precision, ultra and club, ELEY publishes the complete 200-shot proof group, with an X windage coordinate and a Y elevation coordinate for every individual shot fired, together with velocity, group size, shot distribution, date loaded, ballistic coefficient, trajectory and radial dispersion across four barrel types.
This is a 200-shot data set on four platforms, published for the specific batch in your hand. No third-party review approaches that sample size.
3. Test it yourself, through your own barrel.
ELEY operates batch testing centres in the United Kingdom, Hungary, Germany, the United States and Canada, and batch testing is open to anyone. Shooters evaluate up to 20 batches through their own rifle: 10 shots from each batch, the best performers shortlisted, then a further 30 shots from those selections until a 40-shot group size and consolidated score is recorded for each, on electronic targets with bespoke ELEY software and trained Customer Range Officers.
You receive a consolidating score out of a possible 436 for 40 shots on an ISSF target at 50 m, a group size, an RSD figure, an Expected Score for 60 shots out of a possible 654, and a percentile ranking against every batch and barrel combination in ELEY’s database.
That is a review of your rifle with your ammunition, which is the only review that determines your score.
How to Judge a Review You Are Reading
Does it state the batch number? Without it, the result cannot be reproduced or purchased again.
How many shots per product? ELEY screens on 10 and decides on 40. A five-shot group is not a measurement of ammunition.
Was barrel condition controlled? Different products use different lubricants. ELEY uses beeswax-tallow on tenex, match and team, paraffin wax on the recreation and semi-automatic range, EP2723 on rapid fire pistol, ultra and the semi-auto benchrest products, and a dedicated cold-weather lubricant on the biathlon range. A bore running one lubricant will not immediately behave the same on another, so fouling shots after a product change matter.
Was one rifle used? A result from one barrel describes that barrel. ELEY uses four different firearm brands in its own proofing precisely for this reason.
What was measured? Extreme spread from a single group is highly sensitive to one outlier. RSD across a larger sample is far more informative.
What were the conditions? Temperature moves velocity, and velocity interacts with barrel harmonics.
A review that answers these questions is worth reading carefully. A review that does not is best read as an impression rather than a measurement.
Why ELEY Publishes Rather Than Persuades
ELEY has been manufacturing since 1828 and has won 140 Olympic medals since 1964, including 3 gold, 4 silver and 4 bronze at Paris 2024. It could rest the argument there.
Instead, ELEY publishes the accuracy standard for every product, tests 200 rounds from every batch across four firearm brands, makes the full proof data for every batch freely available online, prints the batch code and mean proof velocity on every box, and opens its test ranges to any shooter who wants to measure the result themselves.
The Bottom Line
Read reviews for handling, cleanliness and reliability. For accuracy, go to the data: the published RSD standard for the product, the full 200-shot proof group for your specific batch at eleyxshot.com, and ultimately a batch test through your own barrel. The best ammunition is the production lot that performs best in your rifle, and that is a question only your rifle can answer.
