If you want SLICK, just put a dab of 5W20 on your finger, wipe it down the inside of the boltway of the LE, then smear a dab along the Locking Rib, a little more on the underside of the Rib so that the oil gets to the right side of the boltway in the Body.
NOW cycle the action with your hand OPEN, rotating the WRIST upward from the Trigger position and using the Forefinger to FLIP the Bolt Handle up and curling the fingers to flip it backward.
Now reverse the motion, using the heel of the thumb to slap the bolt forward. A bit of downward pressure (very easy) as your trigger finger seeks the trigger..... and it slaps HOME perfectly with a round up the pipe.
It is AMAZING how fast you can do it with a bit of practice.
Remember, at the Battle of Mons, the British had TWO machine-guns per battalion; the Germans had EIGHT. The Germans, however, thought that the British had far more than they had themselves. "A machine-gun behind every bush," was how the German field report actually read. Actually, it was Tommy Atkins with his Short Lee-Enfield.
The difference was the technique of "flipping" that slick Lee-Enfield bolt after it had had a couple of drops of Rangoon Oil.
