WEll I just completed the Rod Jenkins shooting class, he felt my fingers an said right off that I had a bad release because he could feel caluses. His fingers had no caluses even though he said he shot hrs. daily. I finally learned to relax my right hand while I am shooting, the sore spots are going away. If your hand an fingers are not coming straight back thru the shot, you have tension in your release hand, hope this helps, it helped me.
