You have become a "punch" shooter, or acquired a nice case of target panic. You have to learn to squeeze the trigger and let it be a suprise when it goes off. Probably the best thing to do is to go to a good pro shop, find a good shooter there, and learn how to shoot a back tension release. Once you learn that, and it may take a month or 2 of consistent shooting, you'll whip that trigger release easily. I shoot a back tension all year round, then sight in with my trigger hunting release before the season and all is fine. A lot of shooters go through this, they key is to recognize it, and beat it. Anybody can learn to shoot a back tension release and then hunt with a regular trigger release if they want to learn. Don't let anybody tell you otherwise.
