I've killed 8 or 9 deer with a 223. Most of which were with the Winchester 64gr Power Point. All complete pass throughs, mostly double lung hits. With that being said, I'd opt for the 53TSX in 12 twist 223's and several other options for a rifle with a faster twist. I'd look at some of the heavier TTSX's, the Nosler 64gr BSB or one of the Swifts (62 or 75, depending on twist).

I've never had much luck with accuracy and a 60gr Partition.

Chose your shot and keep the range to a sensible distance. The 223 will do just fine.
