I liver shot my buck last year. He troted off for about 70 yards and that's as far as he went. It was late morning and I was able to keep an eye on him. He tried to get up once afer he bedded down and that was it. Waited a good hour after the last time I saw movement just to make sure he was in fact done for. Odds are yours will do the same and be just where you saw him last. You did the right thing to back out and wait. Good luck and looking forward to the pics...
