That is because your mind is only thinking of aiming and not about releasing. IMO the best way to get over TP is to learn back tension and a surprise release. When you learn to do this - all you do is concentrate on aiming and the release (after a bit of practice) comes on its own - with no mental thought. Its when you " decide" to release that gets you in trouble. The release should not be decided it just comes.

Red Hawk - taping the trigger will probably get you into trouble aslo because you are consiously thinking about firing the release. A fear of missing comes over the mental process and accuracy can go down the drain.

My accuracy has gone up 10 fold since I learned to fire the trigger with my back, and just concentrate on aiming. Its worth the time to learn it IMO

Just my 2 cents
