A year or so ago, my grandson shot in our local club's high youth team and they had a "Father-Son" match, which I agreed to participate because his dad couldn't do it. It was the first time in my life that I fired using a shooting coat...and four positions. At 73 years old, I was very uncomfortable when trying to fit into a shooting jacket and getting into four positions. Thought I'd be crippled for life, as my knees were killing me from kneeling and even found sitting and prone to be painful. By the time I shot offhand (last position), I couldn't hold steady at all. I felt like I was put on a rack for punishment!!!
