I also have several 6.5x55 Swedish Mauser 95 and 96 mausers that I load too modern pressure loads with no issues . The 6.5x55 and 6.5-06 are great I just rebarreled the 6.5-06 too the 6.5-284 for those longer bullets and more mag length . The 6.5 Prc works really well in the mod 70 pre64 . A good gunsmith can easily open the bolt face without any other changes , I just done one of those too . If you really want a guality barrel and a shooter worth waiting for send it too Bartlein and talk too Mark . Good luck
