What type: HBAR, BULL? My 20” bull barrel (BBSS) used .953.... just because it’s a heavy bbl does not always mean it’s going to have a journal over .750. Consult with BA. they will steer you the right way. Also ask them what Ammo they use to test the barrel you have. Mine was 168gr Black hills with Match King bulletts
