Interesting problem: sift through the backstop material and extract the valuable metal fragments from the bullet remains. Those holes aren’t clean, and there will be silver & gold fragments thrown downrange by the bullet penetrations.
The dimensions of the gold 2g pieces shown is 19 x 11.5 x 0.6 in millimeters. So I would guess a Europellet 9mm was used, since the bullet holes are almost as wide as the bars.
Next question: Round nose, truncated cone, or hollow point?

The backstop should be a sloped smooth steel plate leading to a large pool of water.
Silver is dug out of the ground mixed with lead and zinc already so the refining and electro-winning process has already been fine tuned. However, I’m pretty sure the density of the fragments would make silver/lead/gold separation easy.
Even if the gold and lead dust was too hard to separate because of close density, lead melts at below 700, and gold is over twice that.

The silver is much more, as the Germans would say, preiswert.
Silver probably isn’t worth scrounginf from the backstop, but as Robert says, the gold would be. It doesn’t take much at like $1700/troy oz.
(I also don’t believe for a second that, whatever the “artist” claims, it was “shot with a machinegun”.)

I’d rather hoard them to use as barter goods after the zombie/dinosaur/alien apocalypse!

I guess that’s one way to separate the tungsten bars from the gold bars.
