It's always best to take the closest shot possible,but the plan doesn't always go that way.I hunt some very large bean fields with fence rows, draws,and creeks on a large farm,the shots might be 20 yards on out to 506 for my longest shots taking 2 deer in the same field. I try and set up for the closest shots possible within 100 yds,but have taken many in the 300-400 yard range...Did I say I love my 7mm mag.
