I had a major problem. I was shooting a tru fire 360 (heavy pull, long travel) and i switched to a spot hogg wiseguy (feather light, no travel) and I got into a horrible habit of punching the release, I guess because of the drastic change in release. But I started getting stuck just above or below the dot, I could never hold on the dot. If I drifted over the dot I would punch. I could shoot good groups because of the light release but I knew my form was crap.
How I have solved it: I got a tru fire hardcore so I could adjust the poundage. Turned the poundage up very heavy (which I actually like better, really feel the back tension) and I have been shooting blank target at five yards with my eyes closed (close your eyes and there is nothing to panic about). So get your pin centered on the target, close your eyes, and really think about your form, back tension, and executing the shot well. I have been shooting this way for weeks, not even having a spot to look at. I finally put a spot on the target today and shot at twenty yards. Great groups that I actually felt good about my form. I think I'm back!!
