I have both a 22 Mag and a 17 HMR, they are both accurate guns, but the 17 shoots tighter groups that the 22. Smaller critters git the 17 and bigger critters get the 22.
I never got to shoot the first batch of Remington 22 Mag with the VMax, but the current Remington Premier with the VMax shoots 1-1/4" or a little better @ 100yds. In the 17, the CCI does 3/4" to 7/8" pretty much every time.
