LPS, has a MILD steel core
it's not a penetratior
, it's a budge move that gives IMPROVED penetration vs. pure led
then I've seen pure lead go through 1/4 scrap 500yards, mind you it was .50BMG...
as for holing it, I doubt it. crater it up, yeah.
as for this
I know at 100 yards 303 brit, 30-06 and 7.62x39 will all go through 1/2 steel plate
that had to be some MILD
steel, 1/4 hard ox bounces x39 and 7.62 NATO all day long (was tested at 50M from a 240B and RPK)
