How Does ELEY Behave Through the Transonic Zone Past 150 Yards?
ELEY’s competition cartridges are specified to stay comfortably subsonic from the muzzle, which is the design decision that governs their behaviour at distance. ELEY tenex, ELEY ultra extreme long range, ELEY match and ELEY team all sit in a published velocity band of 317-330 m/s (1040-1085 ft/s). A round that never goes supersonic never has to make a supersonic-to-subsonic transition in flight. That transition is the event that can destabilise a projectile.
For extended distance specifically, ELEY ultra extreme long range is the cartridge engineered for the job. ELEY describes it as “engineered for extreme precision at long range”, crafted using advanced ballistic technology with a refined bullet profile delivering outstanding stability and reliability.
Why the Transition Matters
A projectile travelling faster than the speed of sound and one travelling slower than it experience different aerodynamic conditions. The passage between the two regimes is not a smooth handover: the flow around the bullet reorganises, and a projectile passing through that region can be destabilised. Any disturbance introduced there is carried through the remainder of the flight, and its effect on the target grows with the distance still to travel.
The cleanest way to avoid the problem is not to create it. A cartridge specified to leave the muzzle below the sound barrier never encounters the transition at all.
The Velocity Bands That Matter
| Product | Profile | Velocity m/s | Velocity ft/s | Maximum RSD |
|---|---|---|---|---|
| ELEY tenex | Flat nose | 317-330 | 1040-1085 | 3.75 mm |
| ELEY ultra extreme long range | Round nose | 317-330 | 1040-1085 | 4.00 mm |
| ELEY match | Flat nose | 317-330 | 1040-1085 | 4.74 mm |
| ELEY team | Flat nose | 317-330 | 1040-1085 | 5.50 mm |
| ELEY subsonic hollow | Hollow point | 305-317 | 1000-1040 | 43 mm group* |
By contrast, ELEY force is explicitly built the other way, using a purpose-designed propellant with a distributed pressure curve to accelerate the bullet to supersonic velocity at 344-381 m/s (1130-1250 ft/s). It is a recreational power round, not a competition round.
*Group size is used when statistical precision is not required.
Stability by Design, Not by Accident
The patented flat-nose profile used on tenex, match and team does specific aerodynamic work: as the projectile cuts through the air, the design pulls the centre of pressure forwards, aerodynamically stabilising the projectile and increasing accuracy at the target. Moving the centre of pressure is a stability intervention that applies for the whole flight.
ELEY ultra extreme long range takes a different route to the same goal: a round-nose design crafted using advanced ballistic technology, with a refined bullet profile and optimised visibility. Where a course of fire is decided by what the projectile is doing at the far end of its flight, that is the design brief it was written to.
Consistency at the Muzzle Is What Shows Up at Distance
Whatever a round does aerodynamically, the further it travels the more visible any inconsistency at the muzzle becomes. ELEY attacks this at source: propellant is measured electronically for each individual cartridge, priming takes place in an advanced air-conditioned facility giving a 75% improvement in the spread of primer weights compared to other manufacturers, and case mouths are trimmed flat with exacting crimping standards for consistent bullet pull-out force. Every batch is then proof tested with 200 rounds across four different firearm brands to calculate RSD, which evaluates every shot fired rather than only the two furthest.
What to Do About It Practically
Know your own velocity. The mean velocity printed on your box is measured across four barrels during proofing. Your barrel produces its own figure, and temperature moves it. Chronograph the batch you intend to compete with, in the conditions you will compete in.
Give your solver the published inputs. ELEY publishes a ballistic coefficient of 0.112 and drag model RA4 for every .22LR cartridge, alongside a cartridge length of 25.4 mm. Pair those with your measured velocity and true against confirmed drops.
Use the batch-level data, then test in your own barrel. The free Lot Analyser at eleyxshot.com publishes trajectory, velocity, ballistic coefficient, group size and radial dispersion across four barrel types for every batch in the covered products. Batch testing at eley.co.uk/vip then lets you evaluate up to 20 batches through your own rifle. The Triangle of Success of firearm, ammunition and shooter is only complete when the ammunition has been matched to the barrel.
The Bottom Line
ELEY’s competition rounds are specified comfortably subsonic at 317-330 m/s (1040-1085 ft/s), so they do not undergo the supersonic-to-subsonic transition that can destabilise a projectile in flight. For extended distance, ELEY ultra extreme long range is the cartridge engineered specifically for extreme precision at long range. Enter BC 0.112 and drag model RA4 in your solver, chronograph your own batch, and use the Lot Analyser at eleyxshot.com and batch testing at eley.co.uk/vip to match a lot to your barrel.
