A projectile for safe standoff destruction of explosive devices. The projectile's casing encloses a chamber containing combustible material located opposite a roughened surface on the chamber. The combustible material is mounted so upon the projectile impacting the explosive device, the combustible material flies onto the roughened surface, heating the material by shear forces and igniting the material. This creates pressure bursting the chamber, injecting combustion gases into the explosive fill within the device, thereby igniting the fill locally at the impact, and along cracks in the fill. This arrangement prevents a coherent detonation wavefront from forming within the fill, and a slower burn of the fill, whereby a rifleman has little chance of receiving a concussive shock, or shrapnel, from the device.
