I believe that Hornaday has reworked its soft point for the .458, it is now called an interbond (or something like that). There have been some previous threads on this bullet before. I think Hornanday beefed it up to be more like the Woodleigh weldcore.

Comments by those who have used seem to be favorable. I have yet to use the new Hornaday. I do use the 350 gr (in 458) as my practice bullet. I have a large supply of 500 gr Woodleighs in stock, so I will not be making the switch any time soon.
