The class system is REALLY messed up. Multiple animals are in the completely wrong class(pronghorn, elk, bison) and some guns have ridiculous class ranges(.300wm, .375, .450, etc)
To fix this, a list of ethical calibers would be added for each animal. Basically what is in theHunter classic. This would completely get rid of the broken class system.
Example:
Pronghorn- .308, .30-06, 7mm, .300wm, .44, .454, etc
Elk and Wapiti:
.270, .308, .303, 30-30, .30-06, 7mm, 300WM, .45-70 (low grain) , .338, .50 Inline/Caplock
