It's a nice thought to have short range loads and long range loads. But you will have two seperate loads to keep track of, differant zeros, ballistics, etc.
The same load that works at 1000 yards WILL work as well at 100 yards.
The only reason I change up a load is if its for a specific purpose, Hunting, Barrier, Etc. Then I jump over to the load, zero, and use it untill I repeat and go back
Maybe your expirence will be differant, keeping a bunch of loads all straight is a pain. Plus you have to work up a load twice.
My point is, settle on what works for you, if the 168 class bullet shoots well go with it, most myself included dont shoot at 1k near as much as inside 800
