Jackie, any chance you could share your results regarding 6br,105-107 bullets using V-V powders,n140 or n150)? I have always had excellent results with either of the two in heavy bullets. My current rig has .134 freebore,28" Kreiger and i wanted to compare your stuff with mine.. I`m thinking I should be able to crank it a bit with the long freebore,??) thank you for your time......chris 308
