A lot use bi pods. Some just use a back pack. I have changed from a bi pod to my heavy oil skin coat over the rail road tie at the end of the firing line. We all end up sharing a shooting pad that someone has brought and shoot out of the same spot for the most part. Correction on myself the very first fundraising shoot was a silhouette shoot not a big game shoot. So the big game challenge has only ran 6 years. I think I'm getting CRS.
