OP, the beauty of the Pattern 14 and even the Lee magazine equipped Enfield rifles is that they can have their magazines quickly topped up with single rounds through the top as well as filled quickly with the proper charges.
Mauser bolt rifles shared this advantage as well.
Of course, the Garand/Stg44 rifles and later interchangeable magazine semi auto rifles changed all of that.
In properly trained/practiced hands though the charger feeding system is still very effective.
Those pics of how to properly load the chargers are confusing to people that first view them. It doesn't work any other way though.
The chargers used for Mosin Nagant bolt actions and the SVT38 and SVT40 rifles are different and straight.
It can all be confusing.
The Manlicher charging system is similar and used in different milsurps as well, such as French Lebels and Austro Hungarian straight pulls, which also have rimmed cartridges.
There was a good reason for the flange style rims back in the early days of breach loaders, but better manufacturing techniques and better components changed it all to rimless case designs for the most part
There is a lot written on how and why the changes were made. One biggie is eliminating the flange saves a lot of brass over millions of rounds.
