Thank you very much for all the help and information. While I was shooting today I remembered that i was previosly shooting with bare fingers instead of a tab, it had been a few months. So I tried a few shots with bare fingers and my groups moved back to center, so I tried and bought a glove. With the glove my shots stayed center. I had no idea that using a tab would make such a difference. Again thank you for all the help and info.
