ONE LIVE 22 WMR ELP LONG STINGER PROJECTILE. HEADSTAMP C. he 22 WMR Rim-Fire cartridge with the ELP High Speed Stinger (Full Length) projectile as the solution to getting a projectile fired from a 22 WMR through even more water using a long tail spear as with the other ELP Javelin Family products. Objects shot with the High Speed Stinger projectile can then be located using standard magnetic and density based detectors (Carp simply float to the surface for netting). THIS IS NOT THE ELP ‘TRACKER’ GPS TRACKING PROJECTILE. The High Speed Stinger is Vulcanized in the projectile body during normal handling, yet advances forward at the highest speed possible and at over 100,000 RPM’s upon contact leaving the projectile body behind.
