Boy , there are some great aftermarket triggers out there. Look to JARD, RIFLE BASIX and TIMNEY. You can buy triggers down into the OZ's. for weight of pull up. I own both a timney and jard. Both are one pound triggers and both are equaly great. Maybe to light for most hunters but still heavy for the bench and both are adjustable heavier.
You trigger should be adjustable down to around 2lb and should work well for hunting. Do some searching and you may find how to adjust it down from around a 4lb max. What are you looking for , or expect. I loned my rifle to a friend as a backup on a hunting trip some years back. When he tried it out before leaveing on the hunt that 1lb trigger took him by superize. He was not comfortable with it.
