Hello HalfaDouble,Thanks for the reply.

The actions were all "standard" 98 Mauser actions of standard length with very little alteration. Most of the mag boxes also remained unaltered. The idea was to use cheap Military actions with minor alterations. This limited the loaded cartridge OL to 3.25". However, this required a very deep seating of the 400g bullet of the 11.2x72 cartridge. This created a problem back in the day when trying to achieve maximum velocity. With modern powders of today, that is no longer an issue and velocities of 2400 fps are possible.
