If you DO decide to convert, your task will be a lot easier if you retain the original manual extractor design.
If your pic shows the rifle under discussion, IMO it would make up into a PERFECT Schuetzen with its cheekpiece and Swiss buttplate!
Any conversion, IMO, any Ballard conversion at all whether RF or CF, will require a small breechblock insert spanning the two halves of the block face. Not difficult, and fabbing details are amply covered by de Haas' instructions. I've done it 2 ways and both were fine.
IMO the NON-forged Ballard action is NOT suitable for ANY CF cartridge even if loaded to minimum pressures, period, end of discussion. JMOFWIW.
