Rifle shooting out to 400 yards +/-

[Ridge Runner]

adam, read the thread in the beyond 500 yard forum, (7mm AM at .77 miles) I set the scope for windage, parralax, and elevation for each shot, if its questionable I take a spotter shot to be sure I figured right. I use a windmeter, barrometer, and a PDA running a ballistic program for every shot. my program is tweaked from actual shooting to match my POA under different conditions, its not hard to change the POI to hit POA if you measure the conditions that effect bullet flight and adjust to them.
with the technology available today, its not difficult, just takes effort and dedication to get good at it.
