My regular practice distance is 400 yds. and I shoot at an 8in square with a Remington Sendero cal. 7mm Ultra Mag. I use cross sticks from a sitting position fireing a 160 Accubond at 3300 and seldom miss. Scope is a 6.5x20x40 Leupold with target turrets in a Leupold long range base. I usually shoot on 20x. Hitting at 400 yds, even with a cross wind, does not seem too hard.
