Everything I have read regarding the 115gr Berger VLD's shows 54.3 to 54.5 gr. of H4831sc a MAX load. Has anyone out there loaded more with good results? I shot a SUB MOA with 54.5gr and BR2 primers today, with my Marlin XL7. Very happy with the grouping, but was hoping for more muzzle velocity. It was shooting a avg. of about 2976fps. Would a different primer get me more velocity?
