Tradex in Montreal has a case of arsenal-new Swedish M38 barrels. I bought two and that's what I'm using for the 6.5x57R. Be advised that the 6.5x55 has a larger base diameter than the 6.5x57R so it's necessary to cut about 1/2" off the breech end in order to clean up the chamber with the 6.5x57R reamer.
