How does the performance depend on the projectile's starting position?
The exit speed is quite sensitive to the projectile's precise
starting position. It takes only a few millimeters further in or
out to gain or loose significant speed.
This graph shows the measured speed compared to how far the projectile
was inserted into the coil.
| Dist (x) | Muzzle Speed |
|---|---|
| 18.6mm | 4.46 m/s |
| 20.4 | 4.67 |
| 21.5 | 5.00 m/s |
| 22.5 | 4.73 |
| 24.0 | 4.26 |
| 26.8 | 3.73 |
| 28.5 | 1.25 |
A projectile's starting position must tuned to be within a 2mm range to achieve optimum results.
