RE: what possible organs did I hit?
Yajsab- I understand there wasn't a whole lot more you could do, and I applaud you for spending as much time as you did. There are many people that wouldn't do that.
As for the criticisms, don't take them too personally. About this time of year on this board, we get a lot of new folks whose post title is "I shot one now what" or "Shot one looked for a few minutes, couldn't find." stuff like that that is very frustrating to us hunters that do research before we go hunting and do spend hours and days to finding a hit animal.
