A 1:14 twist rate will stabilize the NOE XCB bullet with no problems, and also most jacketed bullets in the 150 grain range. I shoot several 30 cal rifles with 1:14 twist. Larry Gibson’s 30×60 XCB rifle has a 1:16 twist Broughton barrel that also stabilizes the XCB bullet just fine. Good luck with your project.
