Good question ...I would think for a general hunting application then a 4lb to 3lb crisp trigger should handle the majority of things... Weight of the rifle ..type of action and caliber chambered are some of the factors that determine how the trigger poundage is set. Personally I used to set all my stuff at 2 - 2 1/2 lbs and changed it to 3 to 3 1/2 lbs and see no difference but at the lower poundage sometimes I wasn' t frozen in my positiion and the gun went off... pulling some groups
