I have a really nice large ring mauser action that i am thinking about building a 510 whisper on. I would like to know if a 510 whisper can be built on a large ring 98 mauser action. If anyone has any experience I would appreciate the info. I know that a Sako TRG-S action is recommended becuase of the bolt face but I have this action already and I would like to use it if possible. If anyone has dimensions for this cartridge as well as what types of pressures this cartridge generates I would appreciate that as well.

Thanks
