That's going to be a decent starting point with a good target.
Time of flight is barely over 0.5 seconds, and the speed of sound is right around 1100 fps (depending on DA, of course), which puts "clang" at just over 1 second after impact, for a total available time of 1.5 seconds.
It sounds the best when you have at least a 0.2 second gap between last shot and first impact, giving you essentially 1.3 to look baller.
Make sure that your first shot hits the "loudest" part of the steel (you have the time to precisely place the first shot); you don't want the audience to have any doubt that your first shot was a hit.
The 600 has a 1 second time of flight, and about a 1.75 second gap between impact and sound, giving the shooter a pretty solid 2.5 seconds to rip 3 rounds with decent precision.
A good position and being aggressive with the gun will lead to success.
