You are describing beginning stages of target panick.
If you ever get it,you will then understand why hair triggers are bad.
How can you lay your finger on a trigger while aiming if it is set up as a hair trigger.It could go off at anytime without you wanting it too.It is also very difficult to lay the finger on the trigger with any style of glove on.
You havne't learned to aim properly and are trying to get a trigger to fire as you cross the target.You are trying to get it to go off before the pin moves,this will bite most people eventually.
Ask anyone who has gone through the dreaded tp.
I know I am bucking the normal way of thinking here but this is one ofthe biggest misconceptions in archery today along with high letoff.
Hunting releases don't need as much tension as a target release but still require more than most think.
There are a few that require very little tension on their release,I know a few that can maintain a very light feel on the trigger while aiming and then use proper technique to fire the release,but they are few.For most of us,a heavier feel is needed.
