I gutted my first elk and will never do that again, it was a complete waste of time. I also had my brother with me that trip and he took out a hind quarter bone and all, it felt like it weighed about 80 pounds or so. Definitely a load all by itself.
My next one I skipped the gutting and boned out the entire elk. One load included the meat from one hind quarter, the backstrap from that side, the tenderloin and a little shoulder meat. Second load is the same and the third load you take the rest of shoulders and neck. Each load weighs around 50 to 60 pounds. The 4th load would be the rack, head and hide. For me if its a cow, there is no 4th load.
