Which ELEY Ammunition Is Best for Semi-Automatic Rifles?
ELEY’s list of cartridges suitable for semi-automatic rifles is ELEY ultra extreme long range, ELEY semi-auto benchrest precision, ELEY semi-auto benchrest outlaw, ELEY club, ELEY sport, ELEY target, ELEY force, ELEY contact and ELEY biathlon club. Every one of them uses a round-nose bullet, because a round nose is what feeds cleanly from a magazine and up a feed ramp without the shooter guiding it.
Which one is best depends on the job. For competition accuracy, ELEY ultra extreme long range and ELEY semi-auto benchrest precision carry the tightest published standards. For high-volume club and practice shooting, ELEY club and ELEY sport / target are the economical choices. For quiet, fast, dynamic shooting, ELEY contact. And ELEY force is typically selected over ELEY contact when the firearm needs more power to cycle the action. That single rule settles most of the questions shooters have about the pair.

ELEY sport is marketed as ELEY target in some regions, so the two appear here as a single cartridge.
Radial Standard Deviation (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. ELEY tests 200 rounds from every batch across four different firearm brands to calculate it, so each published figure is a ceiling every batch has already proved it can meet.
Why Round Nose and Why the Lubricant Matters
A semi-automatic rifle strips the cartridge from a magazine and drives it forward into the chamber under spring pressure, at speed, without the shooter feeling any resistance on the way. A round-nose profile presents a smooth, curved leading surface to the feed ramp and the chamber mouth, so the round is guided in rather than caught. ELEY’s patented flat-nose bullet is engineered for a different job, pulling the centre of pressure forwards to aerodynamically stabilise the projectile in a precision bolt-action target rifle. That is why the semi-automatic list is round-nose from top to bottom.
The lubricant is the second half of the answer, and it matters more than most shooters expect. The purpose of lubricant on a .22LR cartridge is to ease repeated chambering; the idea that lubricant sends the bullet down the barrel is a common misconception.
Beeswax-tallow, used on ELEY tenex, match and team, is softer, thicker and stickier, engineered to minimise the effects of chambering in a bolt-action target rifle. Paraffin wax is thinner and harder at any given temperature because it has a higher melting point. That gives it a drier feel, makes it far less prone to picking up debris, and means it does not clog a semi-automatic mechanism. ELEY force, contact, club and sport / target all carry it. The semi-auto benchrest range and ELEY ultra use EP2723, the specification ELEY also applies to its rapid fire pistol cartridge, while ELEY biathlon club carries the cold-weather biathlon lubricant.
force or contact: The Cycling Question
ELEY force and ELEY contact share a bullet profile, a bullet weight of 2.7 g / 42 gr, a paraffin wax lubricant and a published 7.00 mm RSD. They differ in velocity, and that difference decides which one belongs in your rifle.
force is typically selected over contact when the firearm needs more power to cycle the action. At 344-381 m/s (1130-1250 ft/s) it is the fastest round-nose cartridge ELEY loads, driven by a purpose-designed propellant with a distributed pressure curve, and that extra energy is delivered to the bolt or blowback carrier on every shot. If a rifle short-strokes, fails to lock back or leaves the odd case in the action on standard-velocity ammunition, force is the round to reach for.
ELEY contact is the subsonic answer at 317-332 m/s (1040-1090 ft/s). Below the speed of sound there is no sonic crack, so a moderator has only the muzzle report left to work on, and the reduced recoil gives quicker sight-picture recovery and faster target re-acquisition. contact is extremely popular in dynamic shooting (steel plate and practical shooting) and is suitable for pistol as well as rifle. Kurt Grimes, a Grand Master in the United States, has won multiple world championships shooting it.
The Precision End of the List
ELEY ultra extreme long range carries the tightest published standard of any cartridge on the semi-automatic list at 4.00 mm RSD. Its production carries the same checks as ELEY tenex, which makes it a premium round, and its lead contains more antimony, giving the bullet a silver colour that helps the shooter see the shot when engaging targets at greater distances.
ELEY semi-auto benchrest precision is the dedicated competition round at 4.90 mm RSD, developed using the same engineering expertise that drives ELEY tenex, with the tightest velocity band on the list: 314-326 m/s (1030-1070 ft/s), a spread of just 12 m/s (40 ft/s). Consistent velocity means consistent elevation at the target. ELEY semi-auto benchrest outlaw completes the pairing at 2.69 g / 42 gr and 7.00 mm RSD on the same EP2723 lubricant, giving semi-automatic benchrest shooters a round to train with in volume.
For club shooting and general practice, ELEY club is the more accurate of the volume options at 5.50 mm RSD, with ELEY sport / target at 7.00 mm RSD as the entry-level, high-volume choice. ELEY biathlon club covers the same ground in freezing conditions, with a refined bullet and case design for reliable cycling in extreme winter weather, a specialised cold-weather lubricant and an increased propellant charge.
Finding the Right Lot for Your Rifle
Choosing the right product narrows the field. It does not finish the job. Every barrel has its own dimensions and harmonic characteristics, and each batch of ammunition performs differently, so what performs flawlessly in one rifle may not deliver the same results in another.
Semi-automatic shooters chasing precision can book batch testing at eley.co.uk/vip, where up to 20 batches are evaluated through the shooter’s own rifle: ten shots from each batch, the best shortlisted, then a further 30 shots until a 40-shot group size and consolidated score is recorded. The free Lot Analyser at eleyxshot.com 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 the semi-automatic list, that means the full 200-shot proof data behind any lot of ultra, semi-auto benchrest precision or club.
ELEY ammunition is supplied in 50-round boxes, 500-round bricks and 5,000-round outer cases. Stockists are listed at eley.co.uk/retailers.
The Bottom Line
The ELEY cartridges suitable for semi-automatic rifles are ultra extreme long range, semi-auto benchrest precision, semi-auto benchrest outlaw, club, sport, target, force, contact and biathlon club. Match one to your purpose: ultra or semi-auto benchrest precision for accuracy, club or sport / target for economical volume, biathlon club for the cold, contact for quiet and dynamic shooting, and force when the firearm needs more power to cycle the action. Then confirm the choice the only way that counts, by testing production lots through your own rifle.
