One of the guys I hunt with uses two loads for his 243.
70 Nosler Ballistic tips for predators and varmints and 90 or 95 grain Noslers for deer . He attaches the appropriate range card to the rifle stock for drops depending on which load he's using.
The downside is the rifle has to be re-zeroed when he changes loads as the harmonics of the barrel "can" change ( along with point of impact, think windage )with different bullet wieghts . It works very well for him.
I use the KISS method, use the appropriate bullet for the largest animal you plan to hunt and over kill everthing smaller. Not the best plan if you want to keep hide though.
