If you actually look at the ballistic coefficients your infinitely better going with a .22 than any of the 6 mm offerings.
The 75 ELDM out of any cartridge that can get it above 3200 feet per second seems to work incredibly well on pdogs, And these days is by far the most popular of the varmint bullet choices that I'm finding from my customers.
You can easily run the 75 ELDM at 3350 from a 22 XC. If you look at the ballistic coefficient it exceeds just about anything offered in a 6 mm and you could always go lighter for short range. You could always go to the 88 ELDM for longer ranges if you felt that was necessary because it actually has the same ballistic coefficient as a Berger 105 hybrid.
