I always come up on the target and can never quite get it to the target when I release, unless I use poor form
Can you explain that a little more? Is it because you can't see the pin on the target or are you releasing before it gets there. I ask because if you were shooting well and now have 300 shots through a new bow the string has probably stretched a little and you may need to adjust your peep, sightand nocking point to compensate for that.
