Casper50, is your rifle really a 9.3x57 ? To me, your rifle looks like made for the German market. In Germany the 9x57 was a much more popular cartridge. The 9.3x57 was a Scandinavian number predominantly, virtually unknown in Germany before the 1970s imports of old Husquarna rifles from Sveden. As the 9.3x57 is better known in America, 9x57 rifles are often mistaken. Don’t rely on the words of a former owner or seller. Check the groove diameter of your barrel. A 9.3 should be .365” minimum, while a 9 is .356” minimum. Or, at least, check the German proofmarks under the barrel. A 9.3 will be marked 9,0 mm or 108.49, if pre-1912, while a 9 mm will be marked 8,7 or 8,8 mm or 118,35 for the bore/land diameter.
