Makes sense. I know they really like two holes as it helps with tracking herd animals and a heavier bullet has more momentum. Launching slower helps the C&Cs stay together as well. The 308 and 7x57 guys shoot A-Frames (and generally think they are the best available bullet) while the 30-06 guy shoots 220 Hornady round noses. While I was there a guy borrowed his 30-06 one day. Took a shot at a Zebra where the bullet hit a tree first, went through the tree and entered the Zebra going sideways. Zebra died quickly.
