Shokk Attack Gun
Each time this unit is chosen to shoot with, roll once to determine the Strength characteristic of this weapon. If the result is 11+ each successful hit inflicts D3 mortal wounds on the target in addition to any normal damage.

In step 1 of the shooting phase you roll for the strength of the

Before firing this weapon, roll to determine the Strength of the shot. if the result is 11+ do not make a wound roll - instead, if the attack hits it causes 3 mortal wounds. The bearer then suffers a mortal wound.
Before firing this weapon is any time in the shooting phase before step 4, where you roll your attacks. So the knight player wouldnt know the strength of the weapon (and neither does the ork player), because RIS has to be played when a knight is targeted, which happens before step 4 of the shooting phase.
