I have the triggers on all of my bolt actions set for a clean, crisp break @ 3 lbs. I can still feel the trigger when hunting and shooting with a light glove on in cold weather.
It really depends on the rifle and its trigger. As explained to me by a gunsmith many years ago, some factory triggers become unsafe if set too low, and will discharger from a small bump. Safety first, and at 3 lbs, it has never been an issue. I get good accuracy, and have a safe rifle; and that's what is most important to me as a hunter and a shooter.
On my lever action rifles, it depends on the make and model as some are not easily adjustable. And many models, gunsmiths will not fool with at all. These, I accept them as is, and learn to shoot that rifle and know the trigger's unique characteristics. With practice over time, I have managed to learn how to get the best consistent accuracy out of that rifle, both at the range and in thee field.
