After posting about scopes previously I've been swayed to go fixed power. Since I'm hunting most likely 200 yards and in it seems 4x is the way to go. So my question to the scope gurus is this, why do they only offer 4x scope in the lower lines but have 6x in the higher grade lines? I'm assuming its that you can get away with cheaper optics for the lower magnification and presumed closer shots but I'd like some info if anyone has it.
