During the time of my career as a professional shikaree ( 1961 to 1970 ) , all the Mauser 98 action rifles brought to India for shikar by my clients HAD to be fed from the magazine. This included best grade bolt rifles built by bespoke English gun houses , such as Holland & Holland and Westley Richards .
Below , I have provided a photograph taken from my soft copy of the 1958 catalog for Holland & Holland . Observe , how it is clearly stated that the rifles must always have their cartridges fed from the magazine.
There used to be an American company however , named " Fred Wells " . In their bespoke bolt rifles , which were built on Mauser 98 actions , they would always bevel the extractor by default in order to allow the extractor to snap over the rim of an extra cartridge.
And yes ... I have seen 3 bolt rifles belonging to my clients , which were built on Mauser 98 actions and had the ejector break , when the operator attempted to snap the extractor over the rim of a cartridge .
The pre 64 Winchester Model 70 , however .... That 1 was a different story.
The operator could " top off " the magazine capacity with 1 extra cartridge by getting the extractor to snap over the rim of the cartridge directly being put in to the breech .
