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.https://uploads.tapatalk-cdn.com/202...cb9d624252.jpghttps://uploads.tapatalk-cdn.com/202...fc410dabec.jpghttps://uploads.tapatalk-cdn.com/202...ccf1eb1efa.jpghttps://uploads.tapatalk-cdn.com/202...bb70234799.jpghttps://uploads.tapatalk-cdn.com/202...332242b54b.jpghttps://uploads.tapatalk-cdn.com/202...0c993e27fa.jpghttps://uploads.tapatalk-cdn.com/202...daca16ee07.jpg
