Yes. Just continue your last target down to 43, 42.7, 42.4 and 42.1. I don't see wasting more ammo on that unless, as you have at the right side of your last target, the left end shows you might be getting into a tight cluster. If you wanted to check Long's 2% rule, I suppose you could go down two more steps to 41.5. You've already shown about +2% from 42.5 is pretty tight with the performance of the 43.3 gr load, so it may be the actual node.
