First of all- this is a hunting game, not a pvp shooter. THIS IS NOT CALL OF DUTY
The weapons in this game have a reputation for hunting because they are clean and effective at harvesting animals. They do not need to be balanced against each other in any way. If someone wants to use one weapon over another that's is their personal choice, buffing/nerfing weapons to sell dlc, promote your personal favorites, or "balance them" is not how it works at all.
The only job any weapon in this game has is to effectively kill the highest class animal in it's range. If a weapon is marked 4-8 it should kill whitetail deer and moose with equal ease as long as the bullet lands where it's supposed to. I've been playing Call of the Wild for about 4 years and I own ALL the dlc so i've compared all the weapons. I recently started to play Way of the Hunter too. The guns are tiered in Way of the Hunter by their energy output based on actual loads for each caliber, THIS WORKS MUCH BETTER THAN CALL OF THE WILD'S BALANCING"
If you don't want people using the .470 on rabbits, introduce a fine for unethical hunting. .470 on a rabbit? -1500 credits in your account
In the real world wildlife agencies set regulations for calibers used on animals. Tennessee had a long running law that minimum bullet diameter for big game was set at .240 inch, meaning the .243 and higher calibers. White Sands Missile range has a set requirement for their Oryx population of .270 minimum caliber. Many African countries set the legal minimum at .375 for dangerous game.
I doubt any player would dislike more realistic ballistics but as it stands a whole friggin lot of us are annoyed by how useless some of them are for even the smallest animals in their range
