That's correct. The berms are in meters out to 500m, with steel hanging at each berm to pound at.
The last target from the rifle line is 720 yards or so and has a steel gong as well.
The size of the gongs... I've got them written down in one of my data books, bu the best thing to do, is grab a tape measure and go out and measure them... put them in your log book and practice your mil'ing.
