2.5 lb is fine for a hunting trigger IMO. There seems to be a fad developed by the internet that everybody needs a 3 lb pack, a 5 lb rifle and a 1.8 lb trigger pull. Chasing unicorns... extremism. Yeah, target shooters benefit with light triggers, but for my camp less than 2 1/2 pound triggers on a hunting rifle is getting in to the danger zone.
Makes me wonder how I killed all those animals with 4-5 lb triggers over the past 50 years.
Yes, I like to stretch the legs on my shots and 500-600+ yd shots are not uncommon, but my rifles do fine at 2.5-3 lbs.
