200 yds is a long shot. Anyone that says there's not more deer lost/wounded with a 700 yd shot is simply wrong in my opinion. There are things like wind and animal movement that simply can't be controlled or quantified.
There probably are more deer wounded at closer range but it's a misleading statistic. Why? Because 100's of thousands more deer are shot at from close range. If an equal number of deer where shot at from 700 plus yards as there are deer shot at under 400 yards then yeah there would be waaay more lost at those long ranges.
