The VZ-24, or any standard length 98 Mauser action, can be reworked to .30-'06 by grinding out some on the ends of the magazine box and feed ramp. It was done to hundreds of thousands of WWII "bringback" Mausers with no problems. It does limit the rifle in that long seated bullets cannot be used, but standard (SAAMI spec) length rounds will work OK.
A small amount of work on the cartridge guides on the bottom of the rails might be needed, but that is no problem.
