Simply because what might be considered good/accurate at 50ft will fall apart @ 50yds when you have high es's/sd's.
Some people might consider this target/ammo/load accurate.

In reality it's nothing more than blammo ammo/plinking ammo/dirt clod killers @ 10 paces. Good old unique and 60fps+ es's. The only reason I use that load is because it doesn't mater what bullet profile I use, anything in the 240gr to 265gr weight range will produce +/- 2" groups with that 11.5gr load of unique. Which means I don't have to put the rear sight up on blocks to get it high enough to hit 6" plates @ 100yds.
@ 50ft that load shoots bugholes in targets, @ 25yds I start to see a flier/1 shot out of the group. @ 50yds the fliers start showing up & @ 100yds I need to be on my game to hit 6" plates. Hense blammo ammo.
