Targets/coloring for 600 yards

[LRRPF52]

This is typically done with pit monkeys on a pitted range where they can pull your target down with the frame, mark your impacts with discs, and raise the frame back up so you can see where your hits were.

I don't even like those because you don't know the sequence of the shots, but they are better than no feedback at all.

For me nowadays, I just shoot freshly-painted steel and spot the impacts with a 20-60x spotting scope. You can video it to see where each shot went too.

If you're doing OCW ladders, you can color the bullet tips like Kswhitetails suggested, then pull the color off with a Q-tip and alcohol.
