A back tension release will not cure target panic, it will make it so you don't know when the shot will go off so you can't mess up the shot before it goes off. Sort of hard to punch the trigger if you don't have a trigger

. It can be done though, backtension releases are not failsafe.
Blind bale, blank bale and aiming exercises will help. Do a search for Target Panic and several great threads will come up describing in detail what to do.
Good luck,
