The VLD is the right bullet for hunting. The BTHP has a thicker jacket that is not intended to produce reliable expansion.
Think of it this way: the VLD will expand/fragment reliably down to impact speeds of 1800 fps. The BTHP may not expand/fragment reliably below 2500 fps (just a guess, it was never tested for this application). The .011 extra BC of the BTHP may allow it to strike a little faster at long range assuming similar MV, but you can't count on it to expand like the VLD at impact velocities down to 1800 fps.
Both bullets are made with the same standards and capable of the same precision. However the VLD is more sensitive to seating depth so it may take you a little longer to optimize your load for it.
For target shooting, the 185 BTHP is a terrific bullet (it's what I personally use in my .308 Palma rifle:
However I always recommend the right tool for the job, and if your job is hunting, then the VLD is the correct choice.
