That is very true.We have a fun shoot every year and it is very entertaining to watch shooters try to hit clay pigeons set out at 500 meters(550 yards) based solely on ballistic calculations and tables.To date the onlyshooters that have been able to hit them consistantly are the shooters that actually checked the point of impact at 550 yards beforehand.The others just raise money for the club by paying anentry feeto try to hit them.
