600 yards is a long ways even with a fantastic rifle and a benchrest. Even the most seasoned rifleman can misread the conditions. The slightest change in wind velocity or direction can cause a tremdous change in impact no matter what cartridge you shoot. It's not a lost cause though you should check into NRA Highpower competitions the course of fire is 200 standing, 200 sitting rapidfire, 300 prone rapid fire and my favorite 600 prone. It's not super expensive and there is a match in most neighborhoods every weekend. You will learn to shoot and read conditions.
