I've run thousands of rounds of both 193 and 855 through my V2. It performs beautifully with it all and can easily do sub-MOA groups.
The only ammo I've had any issues with in my DD is Wolf. This is because DD doesn't over gas their rifles. A lot of manufacturers use larger gas tubes to function with lower quality ammo. I found Wolf causes my V2 to short stroke a few times per mag.
With anything else it runs 100% perfectly.
Enjoy the gun. It's a hell of a nice weapon.
