If my rifle shot the Sierra that well, I would not even consider the Partition. The weight of the bullet will more than offset any potential jacket core separation/penetration issues. The accuracy is essential at extended ranges for deer. The caliber diameter makes a decent size hole with even moderate expansion. If you get moderate expansion you will have a sufficient wound channel coupled with deep penetration from any angle. If have have jacket core separation in a deer with that size of a bullet (very unlikely) you will have a massive wound which drop the deer very quickly. The way I see it, with your cartridge for deer hunting an accurate load is the way to go.
