... but it depends on the bullet, and the cartridge maker.

Cor-Bon DPX bullets tend to be light (even though they have comparable OAL to regular 230), because they are made from bonded copper. They expand reliably, and they penetrate well - primarily because they tend not to fragment on impact.

A 185gr bullet that expands reliably, doesn't disintegrate despite 1075fps velocity, and will reliably penetrate glass on cars is not exactly a bad thing.

So I guess I'm saying that bullet construction matters at least as much as weight.
