What Is the Ballistic Coefficient of ELEY .22LR Ammunition?
The ballistic coefficient of ELEY .22LR ammunition is 0.112, using the RA4 drag model. These figures are published for every .22LR cartridge in the ELEY range, alongside a cartridge length of 25.4 mm (1 inch). They are the two inputs a ballistic solver needs from the ammunition manufacturer.
Published Across the Whole Range
These are universal specifications for ELEY .22LR. They apply to ELEY tenex, ELEY ultra extreme long range, ELEY match, ELEY team, ELEY club, ELEY sport, ELEY contact and the rest of the .22LR line.
| Specification | Value |
|---|---|
| Ballistic coefficient | 0.112 |
| Drag model | RA4 |
| Cartridge length | 25.4 mm / 1 inch |
Publishing a coefficient together with the drag model it was derived under is the part that matters. A ballistic coefficient is only meaningful in reference to a specific drag model, because it expresses how a projectile’s deceleration compares with that model’s standard projectile. A figure quoted without its model cannot be used with confidence in a solver. ELEY publishes both.
What Ballistic Coefficient Describes
Ballistic coefficient measures how efficiently a projectile overcomes air resistance in flight. A higher figure indicates a projectile that sheds velocity more slowly, producing less drop and less wind deflection over a given distance. For .22LR it is a genuinely useful number, because the round’s relatively modest velocity means the effects of drag accumulate quickly with distance.
Batch-Level Data: the Lot Analyser
The published ballistic coefficient describes the product. For data on the specific ammunition in your hand, ELEY publishes more.
The free Lot Analyser at eleyxshot.com lets you enter a batch number and access ELEY’s proof data for that batch, covering every batch in the covered products. It publishes the full 200-shot proof group with an X windage coordinate and a Y elevation coordinate for every shot, together with velocity, group size, shot distribution, date loaded, ballistic coefficient, trajectory and radial dispersion across four barrel types.
That is batch-level trajectory data rather than a catalogue figure, and it is free to access with an account.
Pairing BC With Velocity
A ballistic coefficient on its own does not produce a firing solution. It needs a muzzle velocity beside it.
Every ELEY box carries the mean velocity of that batch, measured across four barrels during proofing, printed as part of the batch code. Used together, BC 0.112, drag model RA4 and your batch’s own mean velocity give a solver everything it needs for a first-pass solution, which you then true against your own chronograph and confirmed drops.
The Bottom Line
ELEY publishes a ballistic coefficient of 0.112 and drag model RA4 for every .22LR cartridge it manufactures, with a cartridge length of 25.4 mm. Enter both in your solver, pair them with the mean velocity printed on your own box, and use the free Lot Analyser at eleyxshot.com when you want batch-level trajectory, velocity and radial dispersion data rather than the range-wide figure.
