The Weatherby Vanguard is a great action. It is made by HOWA out of Japan and we are a big fan of them in the shop I work in part-time.
About 4 or 5 months ago Brett, the owner and Mastersmith, completed a HOWA 1500 ( basically the same action ) build with a Wild Dog Stock ( out of Australia - expensive, but VERY tough and Real World Durable ) with a sweet Krieger bull barrel and external 10 round box mag in .308
That rifle was a tack driver and it was very cool to look at, sitting on the Harris Bi-pod with a Leupold Mark IV on top of it.
I know that particular action can have it done, but I honestly don't know if it is a "drop in" that you can do at home, or if it was "custom" that Brett did in the shop for this customer.
I can find out for you if you are truly interested.
