I had a chamber problem with a Model 1903 Styer Mannlicher in 6.5 X 54, when test fired the case bulged at the base and the case neck shortened to much for my confort. It was suggested that I fire form cases but I chose to cut the barrel down I turn and rechamber the barrel to a correct 6.5X54 and it came out very nice. I do not know if that will work on your JP Sauer or not but something to think.
