Yes it is. Many hunters opt for flatter trajectories ay longer ranges. Think .300 or weatherby magnum’s. At about 250-260 yards a .308 drops 7 to 8 inches with a 165 grain bullet. The idea is that if the gun is sighted in at 3.5 inches high at 100 yards it will be 3.5 inches low at 250. Creating a “point blank” range. Flatter trajectory rounds extend the point blank range. This is just general hunting setup.
I don’t have those exotic calibers. I have 06 and some foreign calibers and I have 45-70. That’s about it. I actually don’t have my rifles to shoot game with.
