Super interesting - thanks Coach!

Interestingly, before I click on the pic to get the (larger) pop-out version, the one in Coach's post has the muzzle diameters at an almost perfect 1:1 scale on my monitor, so it really brings it home
Apologies for the questions, but please can someone shed some light on a few points for a poor gun-less UK GetBigger?
Am I right to assume that's the back of a metal target plate? From what kind of distance if so? (I'm guessing it can't be that gel they use to simulate flesh, or hung paper with no backing??)
