Over the years I have killed most of my food with off-hand shots. I prefer to use a rest if available but I seldom have a chance the way hunting goes around here. I was practicing with my 25-06 out to 200 yds, hit the pie-tin 80% of my shots. I hiked around a bit and to get my lungs and heart moving, my accuracy really suffered. I used to be a better shot but now I am older and fatter. I think I will continue to hold off on any shots longer than 150 w/o a rest. I have made longer shots but pretty sure luck was on my side.
