I don't like the large objectives because I like to mount my scopes low on the rifle to ensure a better cheek position on the stock.This is not only for more accurate shooting but alsobecause the hard kicking rifles will give you a nasty slap on the cheek if your cheek isn't positioned properly.As such I don't use any scope that I can't mount in leupold medium rings and still have room for my butler creek flip uplens caps.I like the ziess conquest 3x9x40 but I am currently using swarovski 3x10x42 scopes on all of my hunting rifles.However my rifles do have heavier contour barrels so even a 44mm objective might fit with the same rings on a rifle with a lighter countour barrel.
