anything that shoots like a light .30-06 IMO isn't kicking much at all. I'm sure in a lightweight setup a .338 federal will kick harder than say a .243, or 7mm-08, though I've sometimes heard neckdown causes more kick than the actual weight of the bullet being shot.

Also, who cares about kick? I've yet to shoot anythign really big, but an unscoped .340wby at about 8lbs, didn't kick much at all either, now that I'm a full sized adult, my .270 gives me alove tap, the .300 and 340 kick and I feel it, but guns kick, who cares? I dont lose a contact....or detach retinas, and can shoot it a few times more without worry, im not going to plink all day with it. I really don't forsee a .375h&h, or .416rigby/rem or .458 lott really being much to deal with either, that .458 may be stiff, but I'm pretty sure I can handle it without much concern. If kick makes your worry about accuracy, then sure but once you learn to control your finger/flinching...then kick really doesn't matter.
