No proven accuracy advantages with any savage action, from the target single shots on down the line to blind mags, hfp, and dbm. As far as your loads fitting the dbm, I do believe that if they fit any of the new savage magazines they will fit all (eg... if it fits in blind will fit in dbm). Not 100% on this, but I do know they use the same boxes for blind and hfp mag options now, I would assume the same size box would be in the dbm, but I'd either call savage or have someone on here measure. Good luck to you!
