RE: First feild dress
Unless the gut area is distrubed or the animal is not found for a period and begins to bloat, then it is a pretty clean job. If you don't like blood, etc it might be a bit tougher but like anything it does get better with experience. The gut area punctures are where some need to take a step back to grab some fresh air, however it is doable and it will not get easier by waiting so better to get it out and clean asap.
Firehawk, I sometimes get a small reaction when I have a fresh knick or cut, it is itchy and seems to swell in the area of the cut (sometimes causing a slight bit of discharge). I know of one guy who develops a itchy rash when handling with his bare hands, he uses top quality disposable exam gloves when handling the game. He also carries a small bottle of the gel antibacterial lotion (basically alcohol) to rinse hands with as a back up measure. If it seems to cause you a problem look into adding some exam gloves to your pack and possibly something to rinse following. They are readily available at drug store or medical supply companies...best of luck!
