Funny how the .358 is handicapped to 200 yards, yet a .338 with the same bullet weight moving a measily 300 fps faster is a hammer on elk to 600 yards. Come on guys, get real....please. Sure, it isn't the flattest shooting round, but it ain't no .357 magnum either. Flinch
Having shot both rounds more than a little out to each round's maximum range (as defined by when it drops below 1800 fps) I can tell you that the flight ballistics are rather dramatically different between the two, at least the way I have my .338 set up.
There's not a high-BC bullet for .358, not a 225 anyway (and the 200's are flying ashtrays). The Partition and Sierra are about the best. Neither of them will hold 1800 fps to 400 yards, though they get close. Both move around in the wind pretty easily, with a .430 BC and 2500 fps starting velocity.
In contrast, the .338 tossing a 225-gn Accubond (BC = .550) at 2850 fps starting speed is one heck of a 600-yard cartridge.
The difference between the two at range is actually pretty dramatic.
