If it's close enough to hear the click do you need to set the trigger?
IMO, "need" can be subjective.
Years ago I tried using the front trigger on a buck after a couple thousand shots year round at the range...I gently applied finger tip pressure, and I gently applied more finger tip pressure, and more finger tip pressure...finally it dawned on me all I was doing was slowly taking up the slack in the front trigger...buck almost walked away.
So I always use the set trigger because I want every shot the same...don't want to even try and remember which trigger operation I'm using for a particular situation...and the good news is it just becomes second nature after range shooting all year.
Even when dove hunting I use the set trigger so my operation is still always the same...but I do relax the adjustment screw a bit so the set trigger wasn't quite as sensitive during fast action.
