honestly I am just getting into the accuret shooting. When I had my Ars ammo was cheap and I had the mid set of shoot 30 rounds at 100 yards and if they all hit a 18x18 inch target I was doing good. Now with 50cent plus a round I have started looking for those tight groups. I am going to get another Ar early this spring and it comes with a 6-9. I do not care for the idea of using sand bags all the time at the range. would you shoot from the sand bag in the woods doubtful. I would try and get something that would do you shooting both target and at the dogs. Though it might not be easy. Though I would not get one that was ok for both but not great for either. You should be able to find one that will do both great or get two. If not go with the one that fit you the best for what you do the most. When I sighted in my muzzleloader a guy at the range ask me why I was shooting like I was. I was sitting on a 5 gallon bucket seat and had a camo painted tripod for a rest. This cause some issues with getting those perfect tight groups, but it was how I would be hunting. He thought that to be odd cause right beside me was a perfectly good bench, but that bench want be sitting there when I hunt.
