Missile bore (impact moling) can be used over what distance range?

Missile bore, or impact moling, is a short-range method used to create a bore path for conduit under obstacles with minimal surface disturbance. It relies on a single impulsive push to drive the bore, so the energy available to advance the line diminishes with distance. Because of this, it’s most effective for relatively short runs. The typical distance range you’ll see for this technique is about 7.6 to 15 meters (roughly 25 to 50 feet), depending on soil conditions and the size of the conduit. Distances beyond this range become impractical with this method and would require other approaches like HDD or longer bore systems.
