The Hornady 250 XTP is NOT made for the pressures or velocity level of the .454 Casull. I'd advise against it's use. Of those mentioned I'd go with the 300 XTP. BUT I don't think any JHP is the proper medicine for a 350 pound hog.
The Freedom Arms bullets (both of them) and the Sierra JSP are hard bullets better suited to such use if jacket bullets are what you wish to use. Me I'd use a hard cast.
