A friend took a smallish WT doe with his this year. He used factory 50gr core-lokts from when his inheritted Rem 600 was new, placed the shot through both lungs at 100' or so and the deer fell over after a short run. I was in on the post-mortem when we butchered it and found he'd hit no bone, the bullet was in fragments, and the onside lung was mush. It was pretty well what we all thought would happen with the bullet involved-fine as long as bone isn't hit,oops if it is. Since the rifle will be used again this year, a batch of ammo has been loaded up with a supply of the 45 gr TSX's I've used in my 1:12 223s for a few seasons. They've worked very reliably on a half dozen WT for Wee Cousin Casey so far, so should work just fine in the deuce.
