I had a problem with trigger punching not too long ago. I use a release that I pull the trigger with my index finger. As I draw my bow, I have my hand in a fist, with the top of the index finger touching the back of the trigger. I anchor and as I do, I slowly move my finger from behind the trigger, to resting very easily on it. As I get the pin around where I want to shoot, I just start to add more and more pressure in slight increments until the bow fires. All in all, from drawing to anchoring to shooting, my index finger is always touching the trigger.
