If you zero that 40 cal at 25yds you will have point blank accuracy out to 75yds . At the muzzle you will be 2" low 25yds to 50yds it will be dead on , 75yds it will be 2" low again , 100yds it will be 6" low . After that the bullet really starts to drop fast
If you have a problem with everybody .
It's not everybody that has the problem
