I have a 3.5-10X50 on one of my 308's and wish I didn't. I just don't need that much field of view. And it (IMO), can make a handsome rifle look rather dorky. Lastly it adds bulk to a place you don't want to add and make it much easier to bump. And adds wieght and significant cost. I like John Barshness's idea that scope without the big bell, can handle recoil better and be more rugged. It makes sense.

I have no problem throwing up a 33mm or even 40mm rifle scope and getting the animl in the sight quickly.
