M98 Mausers don't have to be controlled round feed every time. I've never had a problem with either standard or magnum sporterized Mausers, doing some 'extractor' work to allow them to close over a chambered round. Angles and polish has worked every time.

Simply throw a round in and close the bolt - as all Mausers should be 'fixed' in my humble opinion. They still control round feed from the magazine.

A rifle can be carried with a full mag, and if desired, top round pushed down with another thrown into the chamber and close the bolt, for a 5+ 1 at ready.
