While I don't know if you'd consider them hot enough, the ,22-250 and .223 (ai or standard) are both plenty capable for whitetails. Provided you have a twist rate to stabilize the proper loads, say at least 1-9 in the .223 or 1-12 for the .22-250.
While the Barnes TSX's are undeniably effective my preference is the Nosler 60 grain partition but I'm looking to try the 64 grain Winchester power points so far they seem promising in my .223, accurate and having a reputation for good performance on deer.
