I don't have one, but according to W H B Smith; "1.Cock the gun. 2. Turn the two ears on the magazine clockwise untill red indicator reaches hole marked "Load here". Then turn one more position to expose the loading port. 3. With muzzle pointing down, drop first pellet (head down) into the loading port. Turn mag ears one position and insert next pellet. Continue untill mag is full. Red indicator now appears at loading port. 4.With muzzle pointing down, again open breach; this allows first pellet to drop in when the knurled cap is turned anti clockwise. should the pellet stick, move the cap slightly back and forth untill it drops in. Close the breech and turn the cap clockwise to seal off the breech...Hope this helps; gravity certainly does.
