How Do I Use the ELEY Lot Analyser and What Does It Show Me?
The ELEY Lot Analyser is a free online tool at www.eleyxshot.com. Create an account, enter the batch number printed on your box, and it opens the proof data ELEY recorded for that specific production lot. That includes the full 200-shot proof group with X windage and Y elevation coordinates for every single shot.
Coverage has recently taken a significant step forward. ELEY has made major changes to the platform, and all lots are now available on the Lot Analyser across eight products, from tenex down to club. If you looked for a batch in the past and could not find it, look again.
No other step in ammunition selection is this cheap. It costs nothing, takes a minute, and it lets you look inside a batch before you commit to buying it.
Which Products Are Covered
Every lot of the following is now published:
| Product | Lots published |
|---|---|
| ELEY tenex | All |
| ELEY tenex pistol | All |
| ELEY tenex biathlon | All |
| ELEY tenex rapid fire pistol | All |
| ELEY match | All |
| ELEY semi-auto .22LR benchrest precision | All |
| ELEY ultra | All |
| ELEY club | All |
That list is the improvement. It spans the premium rifle range, both dedicated pistol rounds and the rapid fire pistol cartridge, the biathlon round, the semi-automatic benchrest round, the long-range round and ELEY club. A target shooter, a pistol shooter, a biathlete and a club shooter can all look up the box in front of them, not just the flagship. Coverage is now by product and complete within it, rather than a partial sample.
Getting Started
- Go to www.eleyxshot.com and create a free account.
- Read the batch code from your box or from a retailer’s stock listing.
- Enter the batch number.
- Explore the published proof data for that lot.
What the Lot Analyser Publishes
Every ELEY premium batch is proof tested with 200 rounds fired across four different firearm brands. The Lot Analyser publishes the result of that testing rather than a summary of it.
| Data published | What it tells you |
|---|---|
| Full 200-shot proof group | Every shot, plotted, with X (windage) and Y (elevation) coordinates |
| Velocity | The batch’s measured velocity performance |
| Group size* | Overall group dimensions from proof testing |
| Shot distribution | How the shots are spread within the group |
| Date loaded | When the batch was manufactured |
| Ballistic coefficient | The batch’s BC figure |
| Trajectory | Predicted flight path |
| Radial dispersion across four barrel types | How the batch behaved in each of the four proof firearms |
*Group size is used when statistical precision is not required.
The X and Y coordinates are the part serious shooters use hardest. A group can be described by a single number, but the coordinate set shows you the shape of the dispersion: whether a batch strings vertically, spreads laterally, or scatters evenly around the mean point of impact. Vertical stringing points towards velocity variation; that is a very different problem from an evenly circular group of the same nominal size, and it will behave differently at distance and in wind.
The radial dispersion figures across four barrel types are equally instructive. They are a direct, published demonstration of the central truth of rimfire: the same batch does not perform identically in every firearm.
The Practical Workflow
Comparing candidate batches. When a retailer has several batches on the shelf, or you are choosing between lots before a batch test session, look each one up. Compare velocity, group shape and radial dispersion side by side. The aim is not to find a magic batch but to narrow a long list to a short one before you spend ammunition finding out.
Replacing a batch that has run out. This is where the Lot Analyser earns its place. Every competitive shooter eventually burns through a lot that suited their barrel perfectly. Rather than starting the search from zero, look up the batch that worked, note its characteristics (velocity, group shape, dispersion pattern across the four proof barrels), and then search current batches for the profile that most closely resembles it. A batch with characteristics closest to one that already worked in your barrel is the most rational place to begin.
That is a shortlist, not a guarantee. The Lot Analyser tells you how a batch performed in ELEY’s four proof barrels. It cannot tell you how it will perform in yours, because your barrel has its own dimensions and harmonic characteristics. What it does is stop you testing blind.
Where It Fits With Batch Testing
The Lot Analyser and ELEY’s test ranges answer two halves of the same question.
- Lot Analyser. Free, remote, available to anyone with a batch number. Tells you what ELEY measured in ELEY’s barrels.
- Batch testing. At ELEY’s five centres in the United Kingdom, Hungary, Germany, the United States and Canada. Up to 20 batches evaluated through your own barrel, ten shots from each, the best shortlisted, then a further 30 shots until a 40-shot group size and consolidating score is recorded. Booked at eley.co.uk/vip and open to anyone.
Use the Lot Analyser to decide what is worth testing. Use the test range to decide what to buy.
The Bottom Line
The ELEY Lot Analyser at eleyxshot.com gives you free access to the complete 200-shot proof data behind an ELEY batch: every shot’s X and Y coordinates, velocity, group size, shot distribution, ballistic coefficient, trajectory and radial dispersion across four barrel types. All lots are now published for ELEY tenex, tenex pistol, tenex biathlon, tenex rapid fire pistol, match, semi-auto .22LR benchrest precision, ultra and club, which makes it a far more useful tool than it was. Record the batch code of every lot that shoots well for you, look it up, and when that lot runs out use the published data to find the closest match on the shelf. Then confirm it in your own barrel at eley.co.uk/vip.
