If you want to have one of the ultimate 6mm "Bad Boys" and are willing to pay the price:

1. Expensive chambering. (few people have reamers)
2. Very expensive brass. (now considered obsolete)
3. Excessive barrel wear with repeated shooting.
4. Limited reloading data.

What the HeII, go for it. The most it can cost you is a new barrel after 600-700 shots.

If you are a bit more conservative, as I, think about a 6mm AI or a 6mm-06.
