I want to build a 7mm WSM off of a Winchester or like action. CDNN has the FN SPR actions available in standard short action. Can the bolt face of this action be opened up to accomodate the larger bolt face of the WSM cartridge without difficulty or problems? Would I have problems loading longer rounds in this action? The bottom metal will likely be changed to CDI as I don't know of another option to being able to use the AI magazines.
