OK guys and gals hold on cause I have a whopper to tell!

A few weekends ago my dad and I were out riding through the country and spotted a wild boar on the opposite sideof a peanut field rooting. It was my dads turn to have the first shot so as he got his bipod set up I ranged the distance with the range finder. The range finder maxes at 600 yards and I couldn't get a reading on the range to this pig. In the middle of this peanut field there is a pivotcenter to the irregation system. I ranged to the pivot and it came up to 390 yards. Knowing the pivot is in the center of the field and the pig was on the edge opposite of us we estimated 780 yards. After adjusting his scope he took a steady aim and pulled the trigger. I was looking through the spotting scope and I saw the pig drop. He didn't kick, flinch or anything that I could see. We drove around the field and the pig was laying there. As we got out of the pickup I noticed an exit wound on the opposite side through the shoulder blade. I know he was using his 7 RUM but I'm not sure of the cartridge. We were both surprised to see that effect at that range. If I'd had a video camera I'd sent it to "The Best of the West". It was truly an awsome shot.
