I have no experience with 6,5*68, the only thing I know is that you should never use 8*68s brass for this calibre. The dimensions are not the same, if you have seen pictures or hear about the Blaser r93 that blew up here in Norway, it blew up partly because he used brass from the 8*68 for the 6,5*68 and a bit to much powder of course.

The Voere sounds interesting, 6,5*68 must be a great long range calibre, Good bc on 6,5mm bullets and good speed are always a good combo.
