I'm not sure there are many real world situations that require getting back on target quickly with a scoped magnum rifle. Dangerous game might be the exception but there I'd definitely toss the scope and maybe go with a double rifle ... or a pump action shotgun. Shooting a magnum bolt action typically involves unmounting it from shoulder to reload so muzzle jump is immaterial when reaquiring the target.

Multiple targets and a short window for shooting

If you're removing your rifle from your shoulder to chamber a round, then great. Lots of folks out there jack a round in the chamber while it's still on their shoulder. Unless you're left handed and shooting a righty rifle. Even then, I could chamber a round with my left hand and not remove the rifle from my shoulder.
YMMV
