Thread: Why are 4-20 scopes not more common/popular?

Manufacturing scopes with a range of 5, say 4-20 that work well have only recently become commercially viable in price ranges people want to pay.
Having said that Carlos Hathcock did pretty well with a 10X Unertl and deer are generally a fairly decent sized target unless specifically neck shooting.
The nightforce 2.5-20 NX8 would pretty much cover most bases, rifles, hunting, targets...ranges though if can afford the $$$
