In my previous post, I may have failed to mention that I shot my Cape buffalo with a 400 grain Woodleigh at just under 2100 fps. It seems that is plenty fast enough with good shot placement ; bullet entered just behind rearmost rib on left side, passed through innards, heart (hole of 1 inch diameter +) and out between the front legs.
I had planned to use my NF FPS 300 grain load at 2250 fps, but buddies talked me into going for the 400 grain shot. I had a proven powder recipe using TAC and it worked, but I have since attained the same velocity with VV N133 at pressures under 40,000. Its all good!
N-133 is THE powder in the 405, thanks to you CR!. Before I used RL-15 and that worked ok, but 133 is MUCH better and MUCH cleaner. My load is 52.5gr for the Hornady, TSX, NFs and Woodleighs and 50.5 for the NF solids, all are right around 2250 and POI
