In my opinion, yes. The training area dummy doesn't account for the shear size of the monsters, and how the special ammo can effect them. An example would be Piercing rounds for the guns, which will continue to trigger damage as they pass through monsters, so lining up shots along the length of the entire beast is advantageous, in that case.
The ranged weapons are also geared toward specific ammo, some are better for flame rounds, or piercing rounds, etc, and not just in a damage boost sense. Some weapons fire multiple rounds at a time for certain types, depending on the weapon, for example. There is a large variety of builds for ranged weapons, in that sense.
I played the PS4 version at launch and played the shit out of it, went on a hiatus, and just bought the PC version yesterday. I'm a bit rusty on all the mechanics of the ranged weapons, but I can say they are not shallow.
