Trajectory aside,if you don't shoot targets at 500 yards,you won't have any idea just how accurate you can be at 500 yards with your rifle and load.Even if you can shoot good groups at 100 yards or even 200 yards,they can open up dramatically by 400 yards or 500 yards.If you can't keep all of your shots in the kill zone on a target at 500 yards,the odds of a wounded animal will be very high.
