How do you KNOW which trigger is going to be your second trigger? Do you ALWAYS shoot the front trigger first, giving up the option of using the left, usually tighter choked, barrel first? Stan
From my reading the reasoning for setting the second (rear) trigger pull slightly heavier was to add a margin of safety when firing the
usually fired first (front) trigger. The thought being that the extra 1/2 lb of force required to trip the sear guarded against doubling. Quite frankly I don't know how much this helped stop doubling and I cannot tell the difference between a 3 1/2 pound trigger pull and a 4 pound trigger pull.
