4x16 variables are the best of all worlds.

Deer rifles are often used as varmint rifles.

I have sold all those lower powered variables I have ever owned, but still have one Leupold 3.5-10 AO, 3x12 Burris signature, and a nice 3x9 Bushnell 3200 with rain guard.

I like to be able to examine the rack on a buck to see if he has broken brow tines.

To each his own.
