Having learned from bad experience, I use heavy bullets at moderate speed exclusively. I am a big fan of Kevin Robertson as well as of Elmer Keith, and I found a lot of sound advice in their writing. My formula is using a bullet with a sectional density of more than .300 at a speed of about 720 m/s (about 2300 to 2400 fps). This served me very well and I see no reason to try this modern stuff. Of course this is just my personal opinion, everybody should use what he wants to use.
