A 270 Win firing a 130 grain bullet 3100 fps with a three inch maximum arc over line of sight will cross plane of sight at somewhere between 250 and 260 yards.

This will be dead on at around 35 yards, 3" high at roughly 145 yards, and 3" low around 305 yards.


...new laws were most numerous when the commonwealth was most corrupt. ~ Publius Cornelius Tacitus
