this is called your first and second zero. but every caliber is differant. for example a .223 with a 45 grain lead will be dead on around 40 yards this is first zero and dead again around 200 yards being the second zero. but you still have to make the final adjustments. another example is a heavier and slower bullet. being a 35 remington. with a 200 grain lead your first zero is about 15 yards to have a second zero about the 200 yards mark. your numbers probably would work on a certain gun but i have no idea which one without going threw the books. the general idea works on every gun but the number are differant.
