Lots of misinformation here.
Leupold Rimfire scopes are set to 60 yards NOT 50 yards.
Leupold Centerfire scopes are set to 150 yards NOT 100 yards.
Just because they list 'rimfire parallax' on the specs for the VX1 or VX2 doesn't mean that every VX1 or VX2 is set to 60 yards. It simply means that there is a rimfire version available for sale. Unless your scope has 'rimfire' printed on the box and lazer etched on the bottom of the scope, don't worry about it.
