A few years back, my ex brother and law and I fired my .458 Win Mag. loaded with a Barnes hollowpoint, either 400 or 450 gr, can't remember, at a piece of 5/8" boiler plate. Now I know that is not armor, but it not only penetrated cleanly but actually engraved the rifleing pattern from the gun into the hole it punched.
I would not want to be behind any body armor that thing hit.
