Has anyone tried these? Their website states compatible with conventional load data. Really? The bearing surface on these is looooong! In my 7mm WSM, there would be more bearing surface inside the case than in the neck! It appears the bearing surface is around .640, and I'm wondering if my 9 1/2 twist barrel will even stabilize them. For anyone who has tried them, do you get better accuracy with the bearing surface close to the lands, or loaded like a regular 139 Hornady at the book specs?
