Good point. even if there's no tumble (meaning no longitudinal aspect to the channel size) a wider projectile will leave a wider channel even if it enters and stays head on. Leaving aside the fact that projectiles interacting in hard materials tend to fragment, larger projectile means more and/or larger fragments.
