New LSS Chassis - What to build on it?

I picked up a new (to me) short action MDT LSS Chassis this week (thanks KevWil). Now to decide what to build on it. My first thought is a gun capable of taking deer size game to 600 yards. My second thought is a varmint build.

Suggestions/Thoughts? What would you build on such a chassis

build a 7 twist 243 win for 105-115gr VLD's and do both!

243AI or a 260.

I'm leaning towards a 6.5 Creedmoor in a 24" varmint contour with a Ross Schuler brake added to the end of it.

nice stock, what butt stock do you have on it?
good choice of caliber, which brass are you going to use?

It is the MDT skeleton stock, designed for use with this chassis and the tac21. I will probably use Norma brass, unless Lapua starts making it before I need it.
