They work just fine in inducing fragmentation and thus producing greater terminal effects. It's just that armies found out that they can induce fragmentation just fine using a different mechanism that does not have a Hague convention rule against it, and so are using that instead.
Almost all modern military rounds make use of yaw-induced fragmentation, where they are designed to fly stable in air but not in flesh, and so very rapidly yaw in tissue until they are going sideways, in which direction the bullet does not have sufficient structural strength to stay intact, and so fragments. This has essentially the same effect on the target as using hollow points.
> The 1950s move to the 223 round is pretty explicit on this.
This is false. Because of better yaw characteristics, the 5.56 as adopted had similar lethality as the rounds it replaced, at the expected combat ranges. The problems with 5.56 lethality that have been reported were that the M4 carbines adopted later had too short barrels for the rounds the military was using, and the lower muzzle velocity achieved resulted in impacts where the bullets failed to fragment properly.
