The 7-08 is my favorite deer rifle right now. I use H 380, 46.5 grains. I use a Barnes TSX 140 grain bullet and a COL of 2.73. I routinely shoot a five shot group with all touching at 100 yards. An honest 5/8" five shot group. It is a custom Montana Rifle Company rig.
Be careful extrapolating powder charge between TSX bullets and others. You might start a grain lower with the bullets you mention.
I shot a 246 lb whitetail buck this year with it. Dropped in its tracks. I shot two other deer as well with it. One shot kills with them dropping within a few yards of where they were shot. Ranges 80 to 120 yards. Very good performance with this load.
