Actually, A-Frames tend to exit less often than many other bullets, because their bonded front core expands widely.
In fact, this is a basic characteritsic of bonded bullets. They tend to expand into a more rounded, wider "mushroom" than either monolithics such as the TSX, Nosler E-Tip and Nornady GMX, or mechanically controlled-expansion bullets like the Nosler Partition. The expanded front ends of TSX's and Partitions usually have less frontal area, so tend to punch through the hide on the far side of an animal more often than the wide, rounded mushroom of A-Frames, and other bonded bullets such as the Hornady Interbond, Nosler AccuBond, Norma Oryx, North Fork Soft Point and Woodleigh Weld-Cores.
