usually venison burgers are pretty good, I used to get an endless supply of them from a friend who was trigger happy
lol he used to get the burgers made up at the butchers... think they added pork fat to them so the wernt so dry but i did them on the grilling machine and drained the fat off. he started asking to butcher to put less fat in them for my special diet... damn i miss living close to him now lol
might be worth asking the butcher in future whats in them and if theres fat then he may be able to make you up a batch thats lower in fat
