While I agree that was the original intention, and worked excellently for about 60 combat years and longer for the intermittent conflicts, changing magazines instead of charger loading also works. Slight attention with a light hammer will adjust just about any LE magazine to exit and enter freely. Sniper rifles didn't use chargers with telescope fitted, I'm sure snipers always carried extra loaded magazines.

I believe the LE was the only combat rifle that had an easily replaceable magazine, all the others had integral 5-round magazines. I wonder if the origin of charger loading only is shrouded in the mists of parsimony and English usage, or if it was to be the same as all the other armies, which had to use clips [not chargers] for the same purpose.

However, few things beats the amazement of spectators when they see how quickly and easily chargers work.
