I had the same problem when I use to take a deer to any processor, to the point where I would get as little of the deer as possible ground because I knew I wouldnt eat it and would just eventually throw it away. I started processing my on 2 years ago....as mentioned above by other posters I quickly get the guts out and get it cut up and then on ice for 4-5 days. When I grind mine I use bacon as my fat content and man the difference is night and day. Deer burgers have become a staple at my house since I started self processing so if you are willing to process your own you should find the taste is much better. No gamey taste whatsoever!
