I have mostly converted 1903 Turkish Mausers and 1908 Braz Mausers, but here is a pic of some 7mm VZ24s and a pile of 8mm VZ24 and a VZ24 I converted to 7mmRM by welding the bolt handle, opening the bolt face, opening the feed lips, longer mag box, fiber glass stock, Lothar Walther barrel, drilled and tapped, etc.
