Since there is very little to give perspective to these targets and just how small these groups are, I am providing this example which shows Matt Kline's 3.195" group covered with a $5 Bill.
As you can see, the group leaks out just a hair under the $5. 3 of the bullet holes show their edges just slightly. Pull a bill out of your pocket and immagine 10 shots at 1000 yards inside 1/2 of it. Pretty impressive shooting.
