I don't want to pretend to expertise I don't have.  I haven't
actually conducted any tests, personally.
Let me just note that with the two glasser rounds I was referring to,
the bullets were identical, only the velocity was different.
A cast lead bullet, loaded into a rifle round and fired at rifle
velocities, will also defeat these vests, I believe, despite being
softer than these iron core bullets you mentioned.
