RE: How can I reduce trigger pull weight??
2-1/2 pounds is on the light side, but would not be dangerous if you practice enough with it to be aware of how little pressure is required to set it off! And don't let anyone else use that rifle.
I prefer a double-set trigger for hunting, and have mine set lighter than that. However, I don't set the trigger until the rifle is pointed in the general direction of an identified, legitimate target......
