Does Weight Sorting or Rim Sorting ELEY match Ammunition Improve Groups?
No. Sorting ELEY match by weight or by rim thickness is not necessary. The analytical suite at ELEY’s Sutton Coldfield headquarters, together with 200-round proof testing of every batch across four different firearm brands, delivers consistent manufacturing quality, so the variation a sorting process sets out to find has already been controlled at the point it was created.
The demonstrated gains in match ammunition come from batch-to-barrel matching, not from re-sorting a batch that has already been graded on measured performance. ELEY calculates Radial Standard Deviation (RSD) from that 200-round proof firing and grades the batch on the result. Choosing which of those proven batches suits your barrel is the variable ELEY’s test range data actually measures. That measurement is taken on your own rifle, on electronic targets, over 40 shots.
Grading Is Already a Sort: Performed on 200 Rounds
ELEY tenex, ELEY match and ELEY team are manufactured on the same production line using the same flat-nose bullet, cartridge case, primer, propellant and lubrication. What separates them is measured performance.
Every batch is proof tested on 200 rounds across four different firearm brands, and RSD is calculated from that firing. RSD measures the distance from each shot hole to the group’s centre point, the mean point of impact. The lower the RSD, the closer the group and the more consistent the performance. Unlike extreme spread, which considers only the two furthest shots, RSD evaluates every shot fired. The highest-performing lots become ELEY tenex; the next become ELEY match, then ELEY team.
| Product | Bullet | Weight | Maximum RSD | Lubricant |
|---|---|---|---|---|
| ELEY tenex | Flat-nose | 2.59 g / 40 gr | 3.75 mm | Beeswax-tallow |
| ELEY match | Flat-nose | 2.59 g / 40 gr | 4.74 mm | Beeswax-tallow |
| ELEY team | Flat-nose | 2.59 g / 40 gr | 5.50 mm | Beeswax-tallow |
A box of ELEY match is therefore not an unsorted sample. It is a batch that has already been separated from other batches by its measured RSD across 200 rounds and four rifles, at a sample size and level of instrumentation no home process can reproduce.
What Is Already Controlled Inside the Cartridge
The physical properties a shooter would sort for are controlled during manufacture, on every round:
- Propellant measured electronically for each individual cartridge, guaranteeing consistent powder weight and constant velocity within a batch. Cases of uniform length from a tightly controlled brass alloy ensure each charge burns in a controlled volume.
- Case mouth trimmed flat on every case, ensuring the bullet is always seated perfectly. ELEY match uses a cut mouth case; ELEY team uses precision-engineered trimmed case technology.
- Exacting crimping standards for optimum round-to-round pull-out force, plus heel inspection of the critical heel area on every bullet.
- ELEY prime and an air-conditioned priming facility, delivering a 75 per cent improvement in the spread of primer weights compared with other manufacturers. ELEY prime, introduced in 1979, is the world’s first and only automated dry priming system and won the Queen’s Award for Technology in 1988.
- Temperature-controlled lubrication, Six Sigma methodologies and high-speed electronic visual inspection across the process.
There is also a practical caution. The lubricant on a match cartridge exists to ease repeated chambering, not, as is commonly assumed, to send the bullet down the barrel. The beeswax-tallow on ELEY match is deliberately soft, thick and sticky in order to minimise the effects of chambering, so any handling process that wipes, rolls or abrades rounds risks removing the wax doing that job.
Where the Demonstrated Gains Are
ELEY’s guidance is direct: “Because every barrel has its own unique characteristics, and each batch of ammunition performs differently, a thorough testing process is essential. What performs flawlessly in one barrel may not deliver the same results in another, which is why batch testing is critical to achieving world-class performance.”
At an ELEY test range, up to 20 batches are evaluated through the shooter’s own barrel. Ten shots are fired from each batch, the best-performing batches are shortlisted, and a further 30 shots are fired 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.
Results are reported as a consolidating score (the 40-shot score on an ISSF target at 50 m, maximum 436), an overall group size, an RSD figure, an Expected Score projected to 60 shots (maximum 654), and a percentile ranking against every batch and barrel combination in ELEY’s database. That is a controlled, instrumented comparison producing a number for your barrel. Batch testing is open to anyone, and each year hundreds of target shooters, from club champions to Olympic medallists, use it.
Do the Free Work First
Check the rifle against ELEY’s published specifications. Ideal strike depth is 0.012-0.015 in, measurable with a strike depth gauge; recommended headspace is 0.040-0.041 in. Firing pin springs weaken over thousands of rounds, so both are worth re-checking periodically.
Read the proof data for your batch. A free account at eleyxshot.com opens the Lot Analyser, which now carries all lots of ELEY tenex, tenex pistol, tenex biathlon, tenex rapid fire pistol, match, semi-auto .22LR benchrest precision, ultra and club. For each one it publishes the complete 200-shot proof group with X windage and Y elevation coordinates for every individual shot, plus velocity, group size, date loaded, ballistic coefficient, trajectory and radial dispersion across four barrel types.
The Bottom Line
Weight sorting and rim sorting are not needed. ELEY match has already been sorted, by ELEY, on measured RSD across 200 rounds and four firearm brands, with propellant weighed electronically for every cartridge and primer weight spread improved by 75 per cent through air-conditioned priming. The analytical suite at ELEY HQ and that 200-round proof test across four firearm brands are what deliver consistent manufacturing quality in every box.
The gain ELEY can demonstrate with data is batch-to-barrel matching. Verify the rifle against 0.012-0.015 in strike depth and 0.040-0.041 in headspace, study your batch free at eleyxshot.com, and book a test at eley.co.uk/vip. The firearm, the ammunition and the shooter are the Triangle of Success, and the best ammunition is the production lot that performs best in your rifle.
