I just registered for my first PRS shoot on Aug. 21 in Courtenay BC. I have done one metallic silhouette shoot recently and did some bench rest shooting about 10 years ago. I am almost 74 years old in pretty good shape but find laying prone is tough on my lower back and neck. I was just out in my back yard laying down with a stick for a rifle and it feels pretty tight in my back and neck to look up, not sure what it will feel like with my rifle and scope. I will go out to the range with my gear and check it out. I have a shooting jacket with elbow pads, can I use that? Any pointers for me that will make it easier on my old body? Thanks in advance for any tips.
