Moving onto Bigger Prey?

My main hunting party is 4 wolves at 100% synergy and proficiency. I started going for medium trails when my party was at roughly 40% synergy, and they’ve been successful at bringing in medium & large prey, but I found it easiest to wait until their proficiency and synergy were at least 70% before going on large hunts regularly. 

I think it also depends on that biome you’re in and what your wolves’ specific stats are, but idk much about that.
