The range of adjustment is limited by Lyman to prevent the set trigger from being lightened to the point where we feel it would be unsafe. Adjustment: Turning the adjustment screw (51) clockwise will lighten the set trigger pull turning the screw counter-clockwise will increase it. Be carefol-don't let the light pull catch you by surprise! You may fire the rifle without engaging the set trigger by using only the front trigger. Operation: To engage the set trigger pull the hammer back to full cock, squeeze the rear trigger until a 'click' is felt, then carefully aim and press the front trigger. This system provides either a standard trigger for snap shots while hunting or a more sensitive 'set' trigger for precision shooting.
