I like mine to be 2 to 3 inches high @100 for hunting coyotes. Out to 200 just aim low on the body and aim high on the body @300. At 400, I hold on the top of the body. I really like the Federal Premium 70 gr noslers the best. They drop a little more than the lighter rounds, but buck the wind better. Mine is a short, standard barrel on a HS Precision stock. The longer heavy barrels will produce better results.
