There are getting to be more and more VLD-esque hunting bullets out there. Scirroco, Berger, Accubond to name a few.
A 130gr roundnose out of a 1/10 twist 25-06 might work, but what's the point? If you are thinking anything with a pointed end, and maybe a boat tail, you will need more twist.
Call Sierra, that's a good idea. I've called them a couple of times over the years and they have always been helpful. One time they even did a underground tunnel 200-yard test to answer a question for me pertaining to stability of a 190 SMK out of a 308 twisted 1/12.
