i sight the gun in from a bench and hunt without sticks or bipod. About half my hunting is done from stands. Some stands have good gun rests, most do not. Usually its possible to throw my right leg over my left knee and get a decent supported position that way-i'm a lefty.
On the ground, if no rest is available, i plunk my rear on the ground and assume a good sitting position. My longest muzzleloader shot was made from sitting position: A hog at just over 225 yards.
