The big takeaway is probably "all will work, but bullet construction and velocity makes a huge difference ".
Sometimes that's in practical accuracy. I hit a trotting deer with a reduced recoil 12 gauge slug, without considering that the slug was going 500 fps slower than I was used to. That resulted in a hit about 4" too far back, leading to a lot of tracking. So the slug did its job, but I would have put it in the right place if it had been faster. This speaks to @C-grunt's post about hitting an enemy whose exact distance is unknown: higher velocity/flatter trajectory makes it easier.
