Offhand accuracy at 100 yards

[Jakegsxr11]

I'm wondering what everyone shoots for accuracy off hand at 100 yards. I have never had anyone to shoot with or teach me so I don't really know what to expect. Everyone always talks about accuracy when bench shooting or prone but I want to know what is normal offhand in a hunting situation. I can shoot much better off a rest while prone, and I never had a bench to shoot from. I try to shoot either kneeling or standing like I would out of a ladder stand. I feel I can shoot fairly well at 50 yards but 100 yards is much more difficult. I can usually hit within 2" of a bulls eye at 50 yards but I get maybe 40% of my shots on a paper plate at 100 yards. I find it difficult to hold my scope on the plate during a 100 yard shot, I have also tried using a sling to steady the rifle but that doesn't seem to help much. I get these results with Hornady SST or ELDM it doesn't seem to matter.
