I have used both, and also look forward to using the excellent Lyman Devastator Hp. I have pretty much settled on thre bullets for all my self defense/ hunting needs. Primarily, the Devastator. I penetrates enough in testing, is very accurate, and makews a hole you wouldn't believe. Second, a 250 grain Keith. Ditto, except the 250 is non gas check.. I use it a lot for self defense training. third the lee 310 grain flat point. very accurate, massive penetrationand damage. These three are pretty much interchangable, although i wouldn't want to use the 310 grain in a gun battle around bystanders, in a pinch, it would put a bad guy DOWN.
