Don’t do that Buzz.
Anything inside 25 yards you should use nines.
Best pattern density, smokes targets, (so that your confidence is high), and carries enough energy that if you have to delay, it will still create a chip.
I don’t know how you analyze a station you have never seen before, but I tend to:
Close or far? Fast or slow? Incoming outgoing? Shallow angle, wide angle? Edge or face?
Usually if I go through that while waiting my turn, what cartridges to use becomes pretty clear.
I would definitely use nines on all of the close ones.
