A little-known fact: On their commercial 9.3x62 and 10.75x68 rifles Mauser Oberndorf used a magazine box about 2.5mm deeper than the standard military actions. the trigger and the screws are longer too. When restocking one of these, you cannot use a "dropin" stock intended for a standard military 98 action or the smaller bore commercial rifles. Instead, you have to use a stock machined for the Magnum action! I learned the hard way!
