ELEY vs SK vs RWS vs Lapua: Which Match .22LR Is Best?

No manufacturer is universally best. The highest level of rimfire accuracy is achieved through the Triangle of Success: the right ammunition, the right firearm, and the shooter’s ability to consistently execute every shot. Remove any side of the triangle and performance suffers.

Every rifle barrel has unique dimensions and harmonic characteristics, and every production lot performs slightly differently. This is why elite competitors do not select a brand and stop there. They evaluate multiple production lots before deciding what they will use in competition.

The more useful question is therefore not which brand wins, but which production lot performs best in your rifle, and what each manufacturer gives you to help you find it.

What ELEY Publishes

ELEY’s distinguishing characteristic is the volume of measured data it makes public.

A 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.

Testing on every batch. ELEY tests 200 rounds from every batch across four different firearm brands to calculate RSD. Grading follows the test result rather than preceding it: tenex, match and team are made on the same line from the same components, and the highest-performing batches become tenex.

The proof data behind every batch, free. A free account at eleyxshot.com gives access to the Lot Analyser, which publishes the complete 200-shot proof group for all lots of ELEY tenex, tenex pistol, tenex biathlon, tenex rapid fire pistol, match, semi-auto .22LR benchrest precision, ultra and club, with an X windage coordinate and a Y elevation coordinate for every individual shot, plus velocity, group size, shot distribution, date loaded, ballistic coefficient, trajectory and radial dispersion across four barrel types.

The batch code on every box. The code identifies the loaded product, year of manufacture, loader number, batch number, and the mean velocity of that batch across four barrels during proofing.

How to Compare Any Match .22LR Properly

Most brand comparisons that circulate online are not really brand comparisons. They are single-lot comparisons in a single rifle, and the result reflects the pairing rather than the manufacturer.

If you want an answer you can rely on, control the test.

Use enough shots. ELEY screens batches on 10 shots and decides on 40. Comparisons built on three or five shot groups are dominated by chance.

Test multiple lots per brand. A single lot of any brand is one sample from that manufacturer’s distribution. Comparing one lot of brand A against one lot of brand B tells you about two lots.

Keep barrel condition constant. Clean to the same standard and fire fouling shots before recording. Different products use different lubricants, and a bore that has been running one product will not immediately behave the same on another.

Test in representative conditions. Temperature moves velocity, and velocity interacts with barrel harmonics.

Record batch numbers. A result you cannot trace to a batch number cannot be repeated or bought again.

ELEY’s Own Answer to the Question

ELEY’s position is that the brand argument is settled at the individual barrel, and it has built its infrastructure accordingly.

Each year hundreds of target shooters, from club champions to Olympic medallists, visit ELEY’s five test ranges to find the perfect ammunition match for their barrel. The facilities are in the United Kingdom, Hungary, Germany, the United States and Canada, and batch testing is open to anyone.

At a test range a shooter evaluates up to 20 batches through their own rifle. 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, using electronic targets and bespoke ELEY software.

Because every barrel has its own unique characteristics, and each batch performs differently, what performs flawlessly in one barrel may not deliver the same results in another. This is why batch testing is critical to achieving world-class performance.

What ELEY Brings to the Comparison

A patented flat-nose bullet, developed in 2003, which pulls the centre of pressure forwards as the projectile cuts through the air, aerodynamically stabilising it and increasing accuracy at the target.

ELEY prime, introduced in 1979 and still the world’s first and only automated dry priming system, awarded the Queen’s Award for Technology in 1988. ELEY’s air-conditioned priming facility achieves a 75 per cent improvement in the spread of primer weights compared with other manufacturers.

Discipline-specific engineering beyond the graded range: dedicated pistol, rapid fire pistol, biathlon, long-range, semi-automatic benchrest, semi-automatic and hunting cartridges, each with published specifications rather than a single cartridge asked to serve every application.

A competition record. 140 Olympic medals since 1964, all gold medals at the 2014 World Championships in Granada, 19 of 21 medals at the 2018 Commonwealth Games, and 3 gold, 4 silver and 4 bronze at Paris 2024. ELEY is an ISSF Gold Sponsor.

The Bottom Line

ELEY, SK, RWS and Lapua all manufacture ammunition capable of winning at the highest level, and no brand is more accurate in every rifle. The question that actually determines your score is which production lot performs best in your barrel. ELEY’s answer is to publish the standard every batch must meet, publish the full proof data behind every batch at eleyxshot.com, and open its test ranges to any shooter who wants to prove the answer in their own rifle.
