Something to ask yourself-
What's my honest shooting history like? Am I a 1 shot kill guy or a magazine-full guy? Be honest. A cool head, one-shot killer with three bullets is good to go with the following qualification.
You might pick up something as a backup plan and if you find yourself in a tight spot while hunting, say needing a finishing shot, you can have the extra ammo available. Even cool heads make mistakes or have problems occasionally, but a REALLY cool head takes one shot, 1 kill. Assess your competence and confidence level, factored in with the distance from home, importance of hunt, and effort required to hunt this particular time, etc. This post will be met with skepticism but this is what I would do. I would NEVER assume one ammo will shoot where another does without testing. I'd have to be in a desperate situation to shoot ammo I'd never tested, like a finishing shot scenario, never across a canyon!
