I take on board making comparisons with other sports. It always seems feasible. A challenge has to be humanly possible. Before the advent of modern digital marking. Competitors managed the maximum score of 600. However the variation between 10.0 and 10.9 didn't exist. Hence the introduction. However as we know the competition isn't won by that method. That's why I think it would make an excellent spectator sport.
The only way a match target rifle could score 60 x 10.9. Is by bench clamping. No idea if any manufacturer has replicated this feat. Probably not hence the lack of information.
Is the gun and ammunition up to the task? If you clamp a gun down and shoot at a target, will you get max score?
I have no doubt that a match target air rifle has the capability of constant accuracy. Certainly over 10 metres. The pellets have improved dramatically over the years. However the pellets such as H and N Matchkugeln have always been excellent. These are then sifted and specially selected to produce a consistent projectile. The bench test equipment is a complicated design. We tried many years ago to replicate the process at our club. It was a disaster. Might be easier with a PCP. I've never tried it. However Robin said that he saw the process whilst at MEC. That's proof enough for me. He is also right that in theory a human might replicate the bench test. What isn't in doubt is the unbelievable accuracy these air rifles are capable of.
