I have a pair of new military stepped barrels that were sold to me as 8x57 small ring mauser, apparently they are neither 8x57 or small ring, and have a crown stamp on them, bore swallow a 7mm projectile and a 30-06 cartridge fits the chamber, any ideas? Bore was .305-.306 in the groves with my cheap calipers.
