RE: sniper rifle for hunting?
This should put the MOA discussion into relevant context....
The current record for longest range sniper kill is 2,430 metres (7,972 ft), reportedly accomplished by a Canadian sniper in 2002, during the invasion of Afghanistan, using a .50 BMG McMillan bolt-action rifle. This meant that the round had a flight time of four seconds, and a drop of 44.5m (146 ft). The previous record was held by Carlos Hathcock, achieved during the Vietnam War, at a distance of 2,250 m.
