As with everything there are people whom are experts at what they do,or so they think!!Lots of the time these people talk the other,less knowing folks,into stuff?
For example,here in Pa. it is timberland,most of where you can hunt deer, with out a farmer to let you on his ground is.
A guy at the range uncases his gun and mounted on it is a 4 X 16 adjustable objective Swift scope! He tells me the guy at the gun shop told him that is the scope he needs on that gun for deer hunting!!!!!
OH MY MY!
