Even though different cartridges may take the same bullets, not all the cartridges will extract the same bullet performance. You simply can’t expect a bullet to act the same way from a .308 Win. as it does from a .30-378 Wthby. Mag. It may be traveling nearly 1,000 fps faster from the big gun, and that changes things radically.
A good example of this is the old Nosler Ballistic Tip bullets. For a long time, many hunters thought they were too "soft" and didn’t like them for big game...
