I have had 4 barrels for my K-95 and none have needed fitting. Am down to 3 now as I had a 6.5 swede that had extraction issues so I went with a 6.5x57R instead. Have a 300 WM that is flawless though. Then also have a 5.6x50R. Other than double rifles this rifle is now the only rifle I will fly with. Once I flew with a take-down case I can't go back. Will be headed to Oklahoma again next month with it for Whitetail.
