Zero at 75 or miss(?)

[bluemike807]

I was just reading this on the Wikipedia entry for the .22lr cartridge:

When zeroed for 100 yards (91 m), the trajectory of the standard high-velocity .22 LR with a 40-grain (2.6 g) bullet has a 2.7-inch (69 mm) rise at 50 yards (46 m), and 10.8 inches (270 mm) drop at 150 yards (140 m).[6] A .22 LR rifle needs to be zeroed for 75 yards (69 m) to avoid over-shooting small animals like squirrels at intermediate distances.

Is that true?

Not if you're savvy enough to aim at a 50 yard squirrel's toes.

No. It depends on the size of the kill zone, and assumes, as the previous poster suggests, that you are too lazy to adjust your point of aim. If you know the drop and the range, you don't need a magic zero. 3" high at 50 yards isn't complicated.
