I think in hunting we all evolve, it's just a part of the process. As you shoot more game you change your mind as to what you like or dislike.
We don't always shoot really big animals or animals that are really close so we not only change bullets but we change sighting set ups like scopes, red dots or irons to suit the needs, that's just part of the progression.
I've always said, that's why they make chocolate & vanilla, so we have a choice.
You might say a premium (XXX size) animal requires a premium bullet while deer size game can pretty much be taken with about any well placed bullet within reason. That comes from experience.
