im like pygmy...i zero my deer rifle at 50yds. heck...50yds is a far shot here
then i shoot it at 100 and 150..summer time ill zero at 100...cause its groundhog shootin time...
frizzellr is also right on...tables will get ya close...but dont rely on them. different barrel legnths, lots of shells, wind, etc etc will play its hand in where your bullet ends up
