I asked Scott the same question once.

He said the guy who makes GSSFs Plate racks, Dan Meadows, does not even tell them what steel he uses.

He said that Dan said, if the steel is not ductile enough to bend, it just cracks. That is why after some use, GSSF plates "cup" backwards. They everntually bend so much they pop their welds. They can usually be rewelded once. When they pop the second time, they are so deformed they cannot be rewelded again and it is time to scrap them.

Scott said that when it is time to scrap a GSSF plate, he has Dan weld a piece of square tubing to the back, through which can pass a piece of 1/2" rebar. He then hangs it downrange and uses it for a rifle target.

I have seen and shot these, at the now defunct Pensacola match. On Saturday after the match, they would put them out and bang away at them with rifles until sundown shut the range down.

We are talkiing about a keyhole shape here, the 8" diameter round plate, and the 3"x3" square tab to which the hinge can no longer be welded.

The pounding of all the pistol bullets surface-hardens the surface so much, that hitting it with a .223, .308, or .30-06 ball just takes the paint off; it does not crater.

Although, hitting it on the square tab, which during use on the plate rack does not get hit, does crater. That is enough to prove that this is not rifle rated steel.

Hitting the edge of the plate will also take a chunk out of it as the energy of the hit is more concentrated on a small area.

But who cares?

It is still scrap.
